Suggestions: More Stats for the "Your Collection" World Map Page

Coin collectors, like baseball fans, love stats. Right now our "Your Collection" page lists the number of each grade coin and each coin of various metals which is great. And even though there is a pie graph, which suggests that percentages are calculated somewhere, it doesn't actually tell you what percent of your coins are uncirculated or silver for example. That should be an easy fix.

But I am also purposing adding percentage data on the countries we have coins from. For example, you have coins from 65% of all countries, 96% of all Asian countries, 74% of all European countries, etc.). This is a particularly evil suggestion because collector types hate not having 100% of something. If we see that we have 98% of all African countries we will be crazy until we get that last one.

What say you?

I like the idea of being able to show % of various groupings. In addition to the ones you proposed, I think it would be neat to allow users to define series such as the US State Quarters Series and be able to see what % of that series they have.
