Hi. Tony here from Long Island. I just started my fifth hobby, crh. I bought my first $25 in penny's and it was just as fun as medal detecting. I was able to fill up a pickle jar with all the coppers and loved finding the wheat penny's, oldest was 1922. HH
My first time CRH with my own coins was when my grandfather gave me about 40 rolls of cent to look through. I got about a large pickle jar worth of copper cents (although they currently reside in plastic bags and rolls). There was one roll that had about 45 wheats in it, the oldest being a 1940. You beat my earliest coin. I mostly search through rolls of half dollars my dad buys at the bank, in which he is very lucky. He has about a hundred oz. of silver that has accumulated over the years from crh.
Anyhow, this thread interested me because of your 1922 wheatie. That is a semi-key date in the Lincoln cent series. Check the mintmark to see if one is present; it should be a "D." If there is no mintmark, then you may have a several-hundred-dollar coin in your hands. I'm sure you know about this, but, if not, now you know.
I have always wanted to try metal detecting, but never got the chance. School and band don't help much either. CRH is a good alternative, though. Happy Hunting!
