Yeah, I enjoy them quite a bit. In general, I like very affordable, very old
US coins. Sure, having them in great shape is nice, but not a requirement. Just having an example of some rare old coins in my collection is enough for me.
But I also like getting them for bargain basement prices. For example, I'll snatch up just about any capped half dollar if I can get it for $30 becuase I know that even in poor condition they will sell for more than twice that. Same with the flying cent. It's in terrible condition, but even the bad ones sell for quite a bit more than what I paid. in general, I don't like paying more than $30 for a coin unless it's slabbed, and slabbed coins don't really excite me as much as getting a heavily circulated fine specimen of a very rare or very old coin.
I'd love to get my hands on some poor condition draped coins, or a flowing hair dollar or even flowing hair large cents. Also would like to expand my early commenoratives, if I could get a worn lexington or pilgrim halfs to go with my Booker T, stone mountain, Columbus, Monroe, etc that would be terrific.
