I've decided to sell some coins and I could use a little advice. I searched the internet for references to the 1989 P no mint mark Washington quarter and found a thread on this forum. One of the replies to that thread was from a gentleman who worked in Greenville NC and obtained a large number of these coins while working in a laundromat in 1989. Another reply speculated that as it was thought the coin was the result of a grease filled die that perhaps partial mint mark coins existed as well. As it happens I worked at the movie theatre in Greenville NC in 1989 as a ticket seller and obtained 8 of these coins myself. 2 of my coins indeed show a partially visable mint mark under magnification. Im not an expert but I think this is pretty strong evidence that these coins were indeed the result of a grease filled die. I know the coins have no where near the value they had in 89/90 (yeah missed the boat on that one =/) but given the speculation Harry Foreman made into these coins and the splash they made at the time my question is this. Do you guys think these coins would be more valuable sold individually or sold together as a lot documenting the various stages of the grease filled impressions? Also found in the same rolls of quarters straight from the bank in 1989 were 2 quarter blanks. Do these have numismatic value? Whether they do or do not should they too be included in a lot? (I dunno call it a "They had a really bad QA year at the Philadelphia Mint" collection lol) Any thoughts and guidance would be appreciated.
Coins struck with a grease filled die are entirely different from coins that actually have no mint mark, because for whatever reason the mint mark was not added to the dies. As such, grease filled die strikes carry small premiums, and if any premium is attached to the value will depend greatly on how much of the coin's design is obscured by the grease, as well as collector demand for such strikes.
The blanks, or planchets if they have a raised rim, do have a numismatic premium. The higher the denomination coin the bigger the premium generally. Whether or not to sell them with the rest I don't know, but I would guess seperately.
