When I was a kid I used to wonder about how old the coins I had that I collected. I had some really old ones. I think I had a really bad Roman coin. Bad condition, I mean. But mostly like 1890s stuff, Morgan Dollars and Peace Dollars (who ever though the Morgan dollar woman was hot? I had my eyes on that Peace Dollar girl! wow, what a nymph! OK maybe not a nymph. I forget the word. Waif? I don't know), Anyway I'd think about the germs, maybe on the coins. How long do germs last? What if there's some really old germs on them? Kind of neat to think about even if they're inactive (dead).
