The 1970-D quarters on dime stock are easy to find. Locating genuine dimes on quarter stock is much tougher, or at least always was for me. Thank you, @Fred Weinberg Enjoy!
@CoinBlazer It happens the other way around also.. Here are 1969 and 1970 Quarters struck on Planchets from sheets intended for Dimes.. From my collection -
Thanks for your explanation, @paddyman98. First time seeing this type of error. I wonder how people will notice such error in circulation/coin roll hunting. Are these coins thinner than regular quarters? Are the strikes usually blurry?
Correct. The Blank Planchet will be thinner and the strike would be maybe a bit less in detail but not much. This is why they state the weight of the coin on the slabs so you can see the difference. The opposite goes for @JCro57 's Dime.
Thanks for your additional info, @paddyman98. I wonder if the vending machines will reject these coins, due to their slight weight difference. If yes, may explain why my office's vending machines sometimes reject my BU-graded quarters with no reason...
The reason the dimes on quarter stock are scarcer is because their additional thickness tends to make them jam counting machines. Machine is set for coins the diameter and thickness of a dime, but the quarter stock piece won't pass through. A quarter on dime stock on the other hand will pass right on through a machine set for counting quarters. (Although some machines will reject them for weight reasons.)
These are darn difficult to find. Sometimes the same coin is listed as “struck on thick planchet”. Much less interesting and tends to sell for less. Add the silver version and you’ve got a neat two coin set. Quarters can be on dime and half thickness in both clad and silver. This makes a nice 4 coin set. You get the idea...... Pictures never do these coins justice, as the extra pressure in the chamber is obvious when in hand.
I came across this thread for the first time while looking into a question a newer thread raised, and it made me wonder -- has anyone ever found a 1975 or 1976 dime struck on a planchet punched from 40% silver quarter stock? I'm guessing that none were ever made, but it might have been possible, especially with Mint employee help...
I thought it seemed pretty farfetched. But then I thought of some of the other things I've seen in TPG slabs...
