biokemist6 Bedrock of the Community United States 12437 Posts	Posted 09/23/2010 10:58 am There is virtually no chance at all that this quarter was struck on a foreign planchet because the US Mint no longer mints business strike coins for other countries and has not for many years. The weight is within tolerance for a normal quarter and a post-mint plating job a few micrometers thick would not add a significant amount of weight nor dramatically alter the appearance. Off metal errors are known and a couple have even been discovered here but the weight is not the same as a normal clad quarter. Morgans Dad found one earlier this year. There is one home test you can do to determine if the coin is silver plated- the tissue test. Place a thin tissue over a known clad coin and notice the color- it has a dark grey appearance. Place the tissue over a known silver coin- it will be bright white. Rinse and repeat for your SC quarter. Report this Post to the Staff
razorear Pillar of the Community United States 613 Posts	Posted 09/23/2010 12:10 pm Error Trends Coin Magazine, April 2010 issue, pg.11, "No Copper" Clad Coins. There is a condition seen every so often where the copper core of a clad coin is hidden. It does happen when the outer clad layer gets folded down across the edge of the planchet. It can happen when a slightly worn set of punching dies in a Blanking Press allows the clad layer to extend across the edge of the blank. When that happens, the clad layer covers the copper center core of the blank, giving the impression that there hasn't been a copper core at all. It goes on to say weighing the coin is the best way to diagnose whether it is clad or silver. Report this Post to the Staff

remmy1100 Valued Member United States 380 Posts	Posted 09/24/2010 4:12 pm Something else to consider. when the different layers of metal are put together, they are rolled through a press to make them the correct width for a planchet. This is a layer of Nickel, then copper, then another Nickel. Sometimes the end of the roll, there was not enough copper to make it to the end and the result is a planchet without a copper core which could be the right size just minus the copper core. The weight varies on these errors. Could explain what youy see here, maybe not. just another suggestion. Edited by remmy1100 09/24/2010 4:57 pm Report this Post to the Staff
Awesome Wally Valued Member United States 176 Posts	Posted 09/25/2010 8:15 pm At least I found out today what my "silver" quarter probably is. Apparently the Home Shopping Club sold a set of State Quarters that were plated with either gold or platinum. Looks like I found one of the platinum ones. Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 09/26/2010 10:12 am One way to check is to find a letter and scratch a mark in the reeding of the edge of the coin. This way it shows if the coin has a copper coin or not without ruining the surface of the coin. I've identified a few like this and it was only plated with a foreign substance.
