Thanks COOP for add the right numismatic nomenclature.
@Cu, OK ,if you consider like this is OK for me, your choice. I will not buy this coin as struck on Dime roll.

This may be a wrong stock metal error, thinness of dime. Found for 1965, 1967, 1970-D, 1979. 1970-d easily found weight 4.2 to 4.4 and thinness like dime. circulated value 1970-d 20-30, uncirculated 50-80 Description: look at the thickness of the edge and very weak or poorly defined features. look for very weak details and a quarter that is the thickness of a Roosevelt dime, with very few detailed reeds on the coins edge. |

HGK3: What are the criteria for distinguishing between a rolled thin planchet and a struck on the wrong stock error? Since the dime and quarter are both clad with the same two layers of material, wouldn't a rolled thin planchet look exactly the same as this quarter? If not, what does one look for to determine the difference between the two errors? This error is a quarter with the thickness of a Roosevelt dime, a weight of 4.2-4.4g, with very few detailed reeds on the coins edge and very weak or poorly defined features. The rolled thin planchet are coins struck on a planchet punched out of stock that was rolled too thin on the rolling mill so they are just lower in weight. A 1974 quarter was struck on a rolled-thin planchet and weighs 4.92 grams instead of the normal 5.67 grams which can be much different then the specific error above weight with a thickness of a Roosevelt dime. The rolled thin planchet can theoretically turn up for any year and not just quarters, while this error is known only to be found on 1965, 1967, 1970-D, 1979 quarters so far. Edited by datadragon

Just common sense. Dime thin stock, quarter thick stock.

Silviosi: @Data: Please, can you give the provenance of this information? Interest me. I have information collected from a large variety of different sources as I was learning over the years. In this case however I just used the information from the book Strike it rich with pocket change (Latest 5th edition) starting on p239, 243 since it covered the description of what to look for to identify the error that was missing in this thread, the years of the error known to be found on quarters and covers all of them separately. It also covers the most current suggested values which is why I find it a good source of information to consult. In general the values in that book are accurate since its a recent edition, however 'quality' coins such as top grades can go substantially higher than whats listed as the book is focused more on grades found in pocket change so if you have a prime example you may well exceed the pricing and of course there is always variation in pricing with auctions and demand changes. A great find for $1.50. Quarter struck on dime stock. Right? Yes (on dime thickness stock) which is different than struck onto a dime planchet. It is a quarter with a wrong stock metal error, thinness of dime. NGC lists it as 25c struck on 10c thickness stock (4.2g is the weight in this image).  Edited by datadragon

The slab above is correct. Note the weakness of the strike, because of the thin dime stock stock material. The reverse will be the same:  Note the metal started moving in the center of the design, but not enough metal to form the outer devices and the rims. That is the clue that the planchet thickness was not correct. CoopHome: How can you tell if a planchet is too thin? strike weakness will be present. Edited by coop

Since I got my new scale, I got to weigh several coins. So consistent with all the other data of this error, this error coin of mine weighs 4.28g according to the scale. |

So as per the weight, seem to be a very tinny planchet.
