Maximum Morgan Dollar weight tolerance

claudewill87

Hi,
I have a Morgan that I would probably put at AG3 or G04, which weights around 25.41g. I was wondering if that is in an exceptionable weight tolerance for silver loss? It's something I've had a really long time that I just came across. At most I may have paid around 17$ for it when I acquired it back around 2014.

26.73 +/- 0.097 grams when minted. Seems too light, even for a low grade. Could be struck on a thin planchet or could be a Chinese fake that was worn down to pass as genuine.

Can you post pictures? It does seem a bit light, but if there is excessive wear... well, pictures would help. Cheers, RickO

I think 5% loss is reasonable.

@ricko always appreciates my investigative techniques

@claudewill87

Here is a link to the Report of the Secretary , 1902, if you go to page 191 of the Mint Directors Report, he did a study on silver coins returned to the mint and calculated "percentage of abrasion".

It looks like the average percent loss from abrasion on $164,000.00 worth of silver coins was 5.3%.

There is sooo much info in these old mint reports

Once, out of curiosity, I weighed some groups of "slick" Morgan dollars and Barber silver coins before I sent them to the refiner, and the averaged about 7% light. So, figure that as the low end of genuine but very well worn coins.

I had an opportunity to go to a coin dealer in a city to the south of me, they used both th sigma and the owner inspected it, it is a real Morgan.
Thank you again for everyones help.
