The certified example is 102 grains, this translates to 6.6 grams, the OP coin is 5.9 grams.

The Sacagawea weighs 8.1 grams. So I don't think they used Sacagawea planchets. The mint would have to have received coils/sheets and then ran that through the quarter planchet cutting process. Or they asked the vendor to do the cutting and ship them the quarter sided CuMn planchets. Or the mint workers sanded down the edges to get em to fit the striking chamber.

With the new pics, I'm seeing a regular quarter that might have been plated at one point. The silver color is coming back out.

Yeah, they don't put more than a tiny amount of gold on them, just enough to look ok when they sell them.

If you don't realize how thin that can be, you might have seen the ASEs plated with "160mcg" of ground zero recovered silver. That means that the silver from ONE ASE plates approximately 194,396 coins.

Hi all,
I am a bit confused. A few months ago, I posted a gold coloured Missouri State Quarter and the consensus was that it was gold plated. Reading this thread today makes me question if in fact mine is one struck on an experimental planchet? Or perhaps this one in this thread is?
I will start a new thread, but I thought that post this for comparison might be beneficial in the expert's analysis.

to the CCF!

The 'D' mint mark shows that this is not an experimental planchet quarter. All of the 1999 State Quarter coins struck on experimental planchets were minted in Philidelphia and have the 'P' mint mark

Jess, 1999 was the only year that had the State Quarter experimental planchets as Dearborn also mentioned, so its not possible to have a 2003 on an experimental planchet. The look of the 2003 is plated. The 1999 in question also appears plated and perhaps the silver is coming back after wear and further the experimental coins are quite rare regardless - its not like there are many out there in change just waiting to be found, but I posted the info about them because it was within the weight range and the size was apparently not identical to a typical quarter so exploring the possibility or at least the info is now known for future posts. To be sure it would have to be alloy tested but unless someone like mike byers thinks we are wrong and its likely to be one, its probably just another brick in the wall of plated quarters....


Edit: Good catch Yokozuna, all the known examples are P according to the article.

You triggered a great conversation and had us all looking a little closer at the OP coin.
