[QUOTE="Michael K, post: 4584832, member: 78298"]This is what you have to realize with a foreign planchet. Almost ALL foreign coins have a different SIZE and weight than US coins. This is done deliberately so as not to mix the same size /weight foreign coins with US coins since the foreign coins are usually worth much less. (There are a couple foreign coins that are intentionally the same size/ composition and weight as US coins, but in that case there's no way to tell it's a foreign planchet.) Now, only a coin the same size OR SMALLER can fit in the hub/minting press for whatever denomination coin you are making. So, to be on a foreign planchet the coin has to be smaller than whatever the denomination is. Which would result in incomplete rims, since the planchet was smaller. If your coin has the complete rim it can't be on a foreign planchet. The nickel is interesting, it could be on a thinly rolled planchet and 4.14 is below tolerance. Small premium if that's the case. The penny had some kind of plating applied to it. It is lower weight but not by much. 2.98-3.24 are the specs for copper cents.[/QUOTE]
