I cashier at a gas station, and it's given me an interest in coins. All started when I found a "weird quarter" in my drawer - it was 1964. Looked it up, found out it was silver, and ever since then I've built my collection, almost entirely out of stuff I've pulled out of circulation. It's not a huge collection in the slightest, probably less than 50 coins. But it's a lot of silver.. 5-6 war nickels, about 8 each of various silver dimes and quarters, a 40% silver half, and two silver morgan dollars that somebody wanted to trade for dollar bills.

Besides those, I have a few oddities - a proof quarter (which I found within the last week, actually) and a quarter with one of the faces peeling off. All of these pulled out of circulation because of that one quarter I found years ago.

I don't really have a lot of other major interests, though - I dabble in conlangs from time to time, and pen-and-paper games, but nothing to the extent of my coin collecting.
