no worries on the numbering, I was just curious
The numbering is base58 using the same characters as allowed Bitcoin address characters. These are:
123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz
2 digit counting is like this:
11 12 ... 19 1A 1B ... 1Z 1a 1b ... 1z 21 22 ... 29 2A 2B ...
Coin #100 will be 1NASTY2i
I almost wish I could take it out of it's case just to hold it for real, but I know better!
Taking the coin out of the case and holding it will not damage it. It is silver. Metal.

Interesting thanks, that's good to know! So, i have coin #13 then? 1D?
Yeah, I know it's ok to touch it, I just don't want to bust the case or something dumb. I have other silver coins to play with if i need to

... Thanks again for fixing my account on nastyfans.org.
btw here are some pics I took to show the size in relation to my cable bill envelope and my mouse (and my hand), (Shiny silver ones are with flash set to on).
