Would this pass as Fair or Poor ? I don't know much about coin cleaning but it appears something was applied around the date area, the scan doesn't show to well.
Would a coin like this have any value, i purchased a few silver dollars and this was thrown in with a few other buffaloes that appeared to be acid restored.
if it was in good conditon g4 about 100, its hard to say it good coin to have and a key date buy its pretty banged up, iam sure it has some small value.
Goods go for $50 - $80 on Heritage. Yours does not rate that and it is acid restored. I don't know what they go for, but if someone offered $5, I would take it in a flash.
I do not use a book. What difference does what the book says mean. None are current. Look for yourself http://coins.ha.com/common/view_item.php?Sale_No=68014&Lot_No=61200. And that one is considerably better shape than the OP's BEFORE the acid date. The only acid date selling I know of was a 1913-S type II went for ~$10 and it actually looked like a Buffalo in stead of a flat chunk.
Just for grins, I looked on eBay. Someone tried to sell 3 1914-D's with acid treated dates for $5.99 each. All 3 were definitely in better shape than the OP's and none sold. See http://cgi.ebay.com/1914-D-Buffalo-...mQQptZCoins_US_Individual?hash=item439bc4567a
With the information provided from RLM and the pictures provided of the coin in question, I would say you'd be lucky to get ANY kind of money for this coin. Also, eno, Values aren't determined by a "book" they are determined by the current market value, or the going price, of the coin. Eno, reality is this coin isn't worth much. If you won't sell to RLM, I bet RLM would LOVE to sell to you!
Here's one that went for $6.50, so it's a crap shoot. http://cgi.ebay.com/1914-D-Buffalo-...mQQptZCoins_US_Individual?hash=item3efa7f208b
This coin is good for a harris or whitman album of buffalos. And I think someone overpaid at 6.50 - to me all the hairlines on it made it worse that the original coin in this post. So RLM did some good research for you. I don't see the acid etching that RLM see's, but he knows more about these than I do.
