Last year I bought a couple of mixed lots of pennies (ex-Hiram Brown) in DNW's auctions. On first glance, there were lots of middle to high grade common varieties that made me wonder why Hiram had accumulated them but, on further examination, many of them had little quirks that made them interesting and, obviously to Hiram, collectable.
Only yesterday I noticed that a nice 1863 penny had a small die clash near her head which looks rather like an extra tuft of hair (see below).
If other Forum members bought similar mixed lots, there may be interesting quirks among your coins.
