🧮 Coin Supply Cost Per Coin Calculator

Enter your total spent on storage supplies (tubes, flips, capsules, albums) and your total coin count to see the average storage cost per coin.

Total supply cost ($)

Total coins

The division behind the figure

Everything you have spent on holders, spread evenly over everything you are holding:

cost per coin = total supply cost / total coins

The loaded example, $80 of supplies over 200 coins, gives $0.400 a coin. The result carries three decimal places on purpose: bulk supplies land in fractions of a cent, and a $9 box of 100 flips is $0.090 each, a figure two decimals would round away. Leave the coin count blank and the tool substitutes 1, so the whole $80 appears as the per-coin cost.

Reading the number against what you own

The figure only means something beside the value of the coins it protects. The same $0.400 is absurd on wheat cents worth five cents each - eight times the value of the coin - and trivial on certified coins worth $50, where it is under one percent.

Bulk holdings want tubes. A few cents a coin, and for circulated silver or a cent hoard that is the right answer.
Individual value wants capsules. Anything worth real money justifies the higher cost, because the alternative is surface damage.
Fixed costs fall as you grow. A $30 binder over 200 coins is $0.150 each; over 600 coins it is $0.050, and the next coin only costs you the price of one flip.

Count what the supplies actually cover. Dividing a whole year's spending by the coins in one album understates nothing and overstates everything - use the same scope on both sides of the division.

Frequently asked questions

How much should coin storage cost per coin?

Judge it as a share of value rather than in absolute terms. A few percent of what a coin is worth is easy to justify; spending more on the holder than the coin only makes sense for something you keep for reasons other than money.

Should the album and boxes count in the total?

Yes. They are part of what storing the collection costs, and being one-off purchases they are exactly the costs that fall per coin as it grows.

Why does it show three decimal places?

Because bulk supplies cost fractions of a cent each. A per-coin cost of $0.008 would show as $0.01 at two decimals, which is a 25% error on a figure people multiply by thousands of coins.
