That's... the least wrong list I've seen in a while. I see stuff that shouldn't be on there (all IHCs from 1859 to 1877?), and stuff that maybe shouldn't have been left off (a bunch of Barber dimes and halves in anything better than VG), but it catches most of the good ones and leaves off most of the bad ones.
My completed series from that list includes Lincoln cents, Buffalo nickels, Jefferson nickels, Barber dimes, Winged Liberty dimes, Roosevelt dimes, Washington quarters, Walking Liberty halves, Franklin halves and Peace dollars. The remainder are 3/4 or better for the rest. Only took me 52 years.
I question things like the 1893/2 dime being on there. It's a "key variety" but the 1893-dated coin itself is common. There are more RPDs in the series that are just as scarce.
Yeah, my view. Any list like this is quibblable,(sp?) but not a bad broad stroke. I was thinking about this, for ancients it would have to be a reverse list, list out things NOT rare and assume the other 730,000 types are the rare ones.
I used to get in arg... discussions with a dealer friend of mine about the value of ancients. He would say "Just look it up" and wouldn't really believe me there was no "Red Book" for ancients!
I agree that not all the Indians from 1859-77 should be on there as key dates; the real keys are 1866-72, 1877, 1908-S, and 1909-S. 1873-76 are semi-keys, but you can find about any Indian cent at a coin show. I'm not sure about others but I get copper-nickels IHC's all the time and I've got over 300 average circulated coins from 1880-1908. My take on key dates is that they should be the ones that are actually hard to find, not the exorbitantly expensive pieces that are everywhere on the market.
