Got this back from ANACS a couple weeks ago. Its a 1972 Quarter struck on dime planchet material. I'm not sure, but I think the US Mint released a lot of these errors into circulation. I probably shouldn't have had it slabbed. Anyone know what its worth? It is kind of neat though, its pretty much as thin as a dime. Harry
A dime planchet is much thinner than a quarter planchet. You can see for yourself by placing a dime and a quarter side-by-side and comparing the thickness of each. When quarter planchets were being made a worker mistakenly used a roll of stock intended for dimes. So all the planchets were the diameter of quarter planchets but were the thickness of dime planchets. When the quarters were struck the thin planchets did not fully strike up making for some weak strikes. And all those quarters were very thin and underweight. This is a really cool error. I don't know its value but there are many error collectors who would LOVE to have this coin. I don't think you made a mistake by having it slabbed. You now have an authenticated error.
Harry: Nice find. As I remember, in 1970, there was a 'basket' of dime blanks that were struck as quarters. Value? I haven't seen on up for sale in quite a while.
This is by far the most common date for a dime-stock quarter. Evidently an entire strip of dime stock went through the quarter blanking press. In EF condition, the coin would be worth about $15.
There is one on Ebay Now-Up to $25- If you go to Ebay and put the words Dime Stock in their search engine you will see one selling for $25.00 with 7 hours left to go. I myself have had 2 and still have 1 left. My 1st one sold on Ebay for around $35.00 but I advertized it as a Quarter Struck on a Dime Planchet so after I sent the buyer his coin someone corrected me so I contacted the buyer and offered his money back. He was pleased with my honesty and didn't really know the difference in the coins anyway. I insisted on sending him $10 back so we were both pleased. It is Ebays mission to rid themselves of uneducated people so maybe it should be everyones responsibility to protect the field? I do try but I'll never be some expert because coins isn't my life, they are a hobby. I am now glad to have a place like this to be accepted and not rejected if that is the case...I haven't been here long enough to know. Best of luck with your thin quarter... Dave
They also ran quarter stock through the dime blanking press and struc dimes that were as thick as quarters But those are much tougher to find because fewer got out. The thick dimes tended to get stuck in the counting machines
