Use of spacers to accommodate less than a capacity number of coins in a roll of coins in a case

Abstract

A standard sized coin roll holder is loaded with a stack of alternating coins and spacers such that a variable number of coins can be accommodated in a standard sized holder. The number of coins loaded into the holder can be configured to be one more than the number of spacers, starting with a coin, then a spacer and so on, such that a coin occupies both the first position and the last position in the stack and making a coin face visible at each end. A twenty coin holder can be loaded, for example, with 10 coins and 9 spacers or with 5 coins and 4 spacers. A compressible silicone rubber washer can also be included to account for slight variations in coin thickness, thus securing the stack within the available height inside a closed and sealed case.

DETAILED DESCRIPTION

(6) In the following description, references are made to various embodiments in accordance with which the disclosed subject matter can be practiced. Multiple references to one embodiment or an embodiment do not necessarily refer to the same embodiment. Particular features, structures or characteristics associated with such embodiments can be combined in any suitable manner in various embodiments. References are also made to the accompanying drawings in which the same reference numbers are used throughout to refer to the same or like components.

(7) FIG. 1 illustrates an encapsulated roll 100 of twenty certified Chinese Silver Panda coins 104 in a tamper-evident case 108. The case 108 can be made of plastic, such as polycarbonate, and can be made transparent so that the encapsulated coins are visible from outside the case. The case 108 includes a base 110 and a cover 112, which is attached to the base to encapsulate the roll of coins 104 in the case 108. The cover 112 can be ultrasonically welded or glued to the base 110 in a tamper-evident manner such that if the cover is removed, visibly evident damage to the case will occur. A certification label or card 120 can be held in place in a slot within an interior of the case 108 and encapsulated along with the coins 104. The certification label can be created by a certifying and/or grading authority, such as Numismatic Guaranty Corporation, and can indicate the identity, quality or grade and quantity of coins encapsulated in the case. By loading all of the coins 104 in the same orientation in the roll 100, both the obverse and reverse sides of the coins 104 are visible at opposite ends of the roll 100.

(8) The case 108 can be configured or designed to hold a specific diameter of coin securely without movement. The case can also be configured to hold a specific number of coins, such as twenty, each of a certain thickness, within an internal height of the case. Different cases can be designed with different internal dimensions to hold different numbers and types of coins having different diameters and/or thicknesses.

(9) FIGS. 2A-D illustrate the same case 108 of FIG. 1, but configured to accommodate fewer than twenty coins by using spacers 204 to separate and position the coins 104 within the roll 100. The coins 104 can be loaded in the case 108 or positioned in an alternating or interleaved stack of coins and spacers 204. The stack can be created by starting with a coin, then a spacer and so on, such that a coin occupies both the first position and the last position in the roll and making a coin face visible at each end of the roll 100. By doing this, the number of coins loaded into the case 108 will be one more than the number of spacers 204.

(10) FIGS. 2B and 2D show a view of the case 108 showing a foil hologram that has been hot-stamped to the side of the holder 108.

(11) The spacers 204 can be configured to have a diameter or maximum width substantially matching that of the encapsulated coins, and with an aggregate thickness to occupy any space not occupied by the fewer number of coins, preventing movement within the case 108. The spacers 204 can be made of a translucent or partially translucent material, a transparent material or an opaque material, any of which can, but need not be plastic. For example, the spacers can be made of styrene acrylonitrile resin or polycarbonate. Each spacer can be configured as a hollow cylinder, a solid disc or another hollow or solid shape, such as any polygonal wafer or outline that fits securely within the case. A cylindrical, transparent spacer of sufficient thickness, assuming relatively few coins are encapsulated, can permit the interior faces of coins in the roll to be visible.

(12) As illustrated in FIGS. 2A and 2B, the twenty coin holder 108 is loaded with an alternating stack of five coins and four spacers such that the five coins as separated and positioned by the four spacers within the roll 100. In order to space the coins evenly, the thickness of the omitted coins, which number 15 in this case, can be divided by the number of spacers used, 4 in this case, to determine the thickness of each spacer. Therefore, in this case, each spacer would be 15/4 of the thickness of a coin.

(13) As illustrated in FIGS. 2C and 2D, the twenty coin holder 108 is loaded with an alternating stack of ten coins and nine spacers such that the ten coins are separated and positioned by the nine spacers within the roll 100. In order to space the coins evenly, the thickness of the omitted coins, which number 10 in this case, can be divided by the number of spacers used, 9 in this case, to determine the thickness of each spacer. Therefore, in this case, each spacer would be 10/9 of the thickness of a coin.

(14) More generally, to determine the thickness of each spacer, the aggregate thickness of the coins to be encapsulated can be subtracted from the length of the open space within the case within which the stack of coins and spacers are to be encapsulated, and the resulting value can be divided by one less than the number of coins.

(15) In additional embodiments, different numbers of spacers can be used to occupy space in a standard sized case for fewer than the case's capacity of coins. For example, a single appropriately sized spacer can be positioned substantially in the center of a stack of coins, with approximately half of the included coins positioned contiguously on opposite ends of the roll. Different sized cases can be used to accommodate up to certain capacities of coins, such as up to 5, 10, 20 or 50 coins, with spacers being used to accommodate any empty space in each size of case.

(16) FIGS. 3A, 3B, 4A and 4B illustrate engineering drawings of a twenty coin holder 108 in accordance with two embodiments. FIGS. 3A and 4A show an external elevation view of a closed holder. FIGS. 3B and 4B each show a cross section view of the holder through the plane A shown in FIGS. 3A and 4A respectively. Dimensions in FIGS. 3B and 4B are shown in millimeters. The cross section view of 3B shows the holder configured to hold five coins 104 separated by four spacers 204, as well as one washer 320, while the cross section view of 4B shows the holder configured to hold ten coins 104 separated by nine spacers 204, as well as one washer 320.

(17) The washer 320 can be placed between any of the coins and spacers or at the end of the stack, but in the FIGS. 3B and 4B is shown adjacent a coin at one end of the stack and a spacer. The washer 320 can be made of silicone rubber (referred to as silicon in FIG. 3B) which is flexible and compressible, in order to provide sufficient pressure against the adjacent coin and spacer which secures the stack in place within the holder. A silicone rubber or compressible washer can accommodate slight variations in coin thicknesses while still maintaining an adequate pressure to secure the stack in place. The height of the spacers 204 and the washer 320 can be appropriately configured on a case by case basis to accommodate different numbers and thicknesses of coins.

(18) The washer 320 can also or alternatively be a flexible and/or compressible spacer. In some embodiments, one or more of the spacers 204 can be made of a flexible or compressible material, eliminating the need for a separate washer 320.

(19) FIGS. 5A-C illustrate a spacer 204 configured for use with the embodiment illustrated in FIG. 3B. FIGS. 6A-C illustrate a spacer 204 configured for use with the embodiment illustrated in FIG. 4B. Dimensions are shown in millimeters. The spacers 204 of FIGS. 5 and 6 can be made of transparent styrene acrylonitrile resin.
