1979 LWC Struck On Dime Planchet

Wow, that's nice!

I hope you got a big discount for it being a memorial reverse....

Great coin,
Jim

It would have to be plain. Cents don't have a reeded edge and it probably didn't touch the collar too much anyway. Reeding happens during the striking of the coin in the collar.

Perhaps a matter of semantics, but there is a difference that comes out in value.

An "off metal" coin is a coin struck on a planchet cut to the size for the coin - just of the wrong composition.

This error is different - it is a cent struck on a dime planchet - not an 'off metal strike'.

There is also such thing as 'wrong stock strike' coins where, say, clad made for a dime is run through the blanking press for quarters producing quarters as thin as dimes.

Besides being thinner, they are also weaker struck:

I want one of these so bad ! I ll keep looking .

Very cool... What kind of thing happens in the mint for the wrong planchet or wrong stock? Just plain old human error?

The coin will be larger than the normal planchet size in the case of the cent on a dime planchet. But the Cent die being wider will have some devices fall over the edge of the planchet. The more off centered the planchet, the more one area will be missing devices.

Note at 3:00 the rim shows and at 10:00 the devices fall over the edge of the planchet.

In the case of the 1970-D quarter on dime stock, the metal used to cut the planchets was dime thickness material. Cut into blanks, upset into planchets and struck. This is a know error as there are several of these known. The quarters will have the reeding on the edge of the coins, like normal, but just the thickness of a dime. So if you had received a OBW roll there would have been more than 40 quarters in that roll. (Not all would have been that way) So the thickness is different not the outside diameter.
