Please double check these numbers. I'm quite sure this isn't right somewhere, either in the calculations, or in the coin counts. I'm not sure what all the numbers mean.
Part of the uncertainty comes from not knowing which coins each of these are. I think ungraded coins are included in the figures, which is probably skewing results somehow. We should probably redo the numbers with only graded coins, so we don't double count anything. We can work off of unique serial numbers, so we know what's what.
I will revisit this later when I've got more time. I may use this project as a test for the coin compendium, to see if it can automatically generate these numbers for us, without needing to do it manually.
These numbers should be considered to be off by a little bit until I take the time to verify each coin, or make the coin compendium do it for me.
