howdie yall, I hope I came back to the right spot for this, I have bought several Morgan dollars off ebay recently and I have noticed a drop in weight, question is ,isn`t all coins of the same denomation supposed to weigh ths same?all of my own weighed in at between 26.5 -26.6 I`m not talking about 1/10th of ag but up to 8/10th difference between coins minted within several years of each other, and the coins are in f to a uc cond so they shouldnt be that much wear, well i`m just dumb in al but also confused , thanks
Rest in Peace

Hi GF and welcome to the forum! Lots of friendly folk here and plenty of expertise among the membership.

A Morgan weighs 412.5 grains (26.730 grams) when it's minted. The series was consistent throughout its mintage. A well-circulated (G-04 at best) 79CC Morgan I have weighs 398.2 grains (25.80 grams). Any Morgan which weighs less than this is suspect. A pot metal casting counterfeit Morgan I have weighs 380.0 grains (24.62 grams). For best weight measurement, the resolution of the scales needs to be to at least in the hundredths for best accuracy; also ensure the scales are calibrated. Do you have a means by which to be more precise in the Morgans' weights by grades? Also, there's a specific gravity test, but that requires a mechanical beam balance or the equivalent.

hello and thanks for the reply, I have 73 morgans and until last week they all weighed almost the same + - 1 or 2 g, but last wk I bought some and I weighed them and I was shocked, out of five only one made it to 26.7, two weigh 25.4 and two weigh 25.8, I was looking at a gram being gone it probaly was just silver, my luck but I use digital scales for my weight, 150g capicity with graduation :0.1g I can float one or two grains but I sink on grams, this didnt sound right and I was just wondering if all of them were supposed to be same weight or if anything was changed over the years, out of my original 68 coins none weighs over 26.7 and none under 26.5, I appericate your feedback and i`ll keep my eyes open and my wallet shut, have a good day....
Rest in Peace

GF, unless they're very very worn, those Morgans you have under 25.8xx grams are highly suspect; if they're AU or uncirculated, they would be absolutely fake if under 26.7 grams. Sounds like you got a bad lot. I hope you didn't get burned too badly for them. There's some who collect counterfeits, many of whom have them largely for educational purposes including myself, but the going price on a Morgan counterfeit is ten to twenty bucks.

Main thing is be sure your scale is working properly. Put in new batteries, check with coins of different denominations, then check you old ones again. If your scale is fairly accurate and you keep getting those low readings, you probably have fakes. There is some kind of law that governs that they must have something stamped on the coin stating it is a fake or it could be conficated if attempting to sell. However, tuff law to inforce. If you have access to any coin shows, take it there and check with some of the dealers. They usually can spot fakes resonably well if in the business long enough.

I would also think that there has to be a way with the scale manufacturere to either calibrate the scale OR away to to make adjustements versus a KNOWN weight if you will--Remember in the "old" days, they used good old "mechanical" scales" using "known" weights, like the justice scales if you know what I mean. I currently use a very old grams scale, even so, it is very accurate--
