I have been collecting and buying/selling for a few years, and am starting to hone in on
Indian Head cents. I have a
Cherry Pickers Guide, but haven't purchased the attribution guide yet. My question is how do I determine value of varieties that aren't published in the
Cherry Pickers Guide? I just bought this 1880 that I believe is a snow-3f which was attributed last year by Richard snow and submitted by one of the cc members. Is there a number somewhere for premium over book value of a non variety coin? Thanks
