Use of spacers to accommodate less than a capacity number of coins in a roll of coins in a case
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.
1. A method comprising:
identifying a quantity of coins to include in a transparent plastic case having a base and a cover, the case being configured to hold a capacity number of coins;
determining an aggregate thickness of an omitted number of coins, the omitted number of coins representing a difference between the capacity number of coins and the quantity of coins;
determining a common thickness for each of a plurality of spacers to include with the quantity of coins in the case by dividing the aggregate thickness of the omitted number of coins by one less than the quantity of coins;
inserting the quantity of coins and the plurality of spacers into the case such that the quantity of coins and the plurality of spacers are interleaved in an alternating sequence in a stack within the case; and
attaching the cover to the base by ultrasonic welding after inserting the quantity of coins and the plurality of spacers into the case.
2. The method of claim 1 , wherein the aggregate thickness of the omitted number of coins is determined by subtracting an aggregate thickness of the quantity of coins from an aggregate thickness of the capacity number of coins.
3. The method of claim 1 , wherein one of the coins in the alternating sequence is disposed in a first position in the stack and another of the coins is disposed in a last position in the stack, and wherein the stack is secured by the case preventing movement of the coins and spacers within the case.
4. The method of claim 1 , wherein the cover is attached to the base in a tamper-evident manner.
5. The method of claim 1 , wherein at least one of the spacers is a compressible washer.
6. The method of claim 1 , wherein at least one of the spacers is substantially incompressible.
7. A method comprising:
identifying a quantity of coins to include in a transparent plastic case having a base and a cover, the case being configured to hold a capacity number of coins within an interior height inside the case;
determining an aggregate thickness of a plurality of spacers to include with the quantity of coins in the case by subtracting an aggregate thickness of the quantity of coins from the interior height;
determining a common thickness for each of the plurality of spacers to include with the quantity of coins in the case by dividing the aggregate thickness of a plurality of spacers by one less than the quantity of coins;
inserting the quantity of coins and the plurality of spacers into the case such that the quantity of coins and the plurality of spacers are interleaved in an alternating sequence in a stack within the case; and
attaching the cover to the base by ultrasonic welding after inserting the quantity of coins and the plurality of spacers into the case.
8. The method of claim 7 , wherein the stack further comprises a compressible washer, and wherein the aggregate thickness of the plurality of spacers is determined by further subtracting a thickness of the compressible washer from the interior height inside the case.
9. The method of claim 7 , wherein one of the coins in the alternating sequence is disposed in a first position in the stack and another of the coins is disposed in a last position in the stack, and wherein the stack is secured by the case preventing movement of the coins and spacers within the case.
10. The method of claim 7 , wherein the cover is attached to the base in a tamper-evident manner.
11. The method of claim 7 , wherein at least one of the spacers is a compressible washer.
12. The method of claim 7 , wherein at least one of the spacers is substantially incompressible.
