US Pattern Questions

RKKay

It is generally accepted that the 1854 J-159a electrotype is a Mint-made electro. My first question is what has led experts to the conclusion that this was Mint-made? My second question is, if it is true that the J-159a is Mint-made, is there any reason to believe the Mint did not make electro's of the J-160 and J-163? If there is a reason to believe they did not do so, what is that reason?

I know that the mint did make electro's of several of their patterns - whether the Mint recorded creating electro's is another debate entirely.

Can't help you with your specific question, but MrEureka should be around here shortly

J-159A on Heritage

It is generally accepted that the 1854 J-159a electrotype is a Mint-made electro.

It used to be generally accepted. Now, we're not even sure if they're really electrotypes. The seams on these coins may have been caused in some other way. One possibility is that the coins are copper-plated. More tests need to be done.

Thanks Rick. Is your word processor warm?

For starters, I'd want to compare the specific gravity of the copper/bronze pieces that have a seam with the ones that don't (if they exist), and with the white metal ones.
