A while back I bought a lot of 15 large cents that were damaged, corroded, holed, details, etc. While I was looking through them and doing a (little!) bit of cleaning I was working on a braided hair LC that was pretty corroded, I got to a point where I could just make out the date and saw to my shock that it was an 1857 small date variety! It's not a beautiful coin, It's good for a filler date, its still in pretty bad shape but it kept me from having to spend $200+ on one for my collection (yet, lol) Feel free to post any of your unexpected lucky finds from large lots/rolls!
