When this thread started I had just joined realcent a few months earlier. I probably didn't chime in at the time because I was fully in the grip of sorting fever and only posted to the monthly tally boards
In the beginning, I was all about the copper, nothing else. Pretty quickly I started separating the wheats, and selling them in bundles of $25 face as they accumulated. Naturally, any nicer examples say pre-1940 I hung onto.
That led to my eventually honing a "feel" for anything Lincoln that looked out of the ordinary. Sorted out both a '55 and a '72 doubled die that first summer. Not the Number 1 versions, but still respectable PCGS slabs (thanks to barrytrot)
Then, in the course of many dump runs, I got into swiping all that Canadian coin from the Penny Arcades. Which led to all kinds of coin collecting opportunities.
My point is that I believe if your interests are varied you're more likely to stick with whatever this weird obsession is we all seem to have. That's kind of where I am now. Not a major sorter or collector anymore, but not ready to give it up entirely. Age will do that to you
