No, this is *not* a good forgery.

Even allowing for metal movement from a wire brush, the proportions are all wrong. On first glance, my eyes crossed; it just ain't right for a 1921 Morgan.

Specifically: The arrow fletches are wrong. The shape of the eagle's head is wrong. The date numeral spacing and number height-width proportion is wrong. There's too little "white space" in "In God we trust," even allowing for metal flow.

Ugh. It hurts to look at.
The best thing about a bicycle is that it uses no gasoline, therefore the chance of fiery death is greatly reduced.

Dcreek1968 If I understand you correctly - you would put the water and container on the scale and zero it out. Then adding the coin would give you the same weight as in air.

You need to weigh it hanging in water. The analytical scale I use (a 4 beam Ohaus balance) has a hook above the normal pan and a free arm that can support the water and container.

Here is a sketch I made of how it works using a picture of an Ohaus scale like mine. The arm in the Photo is in the balse - you just raise it to do the test.




Here is another set up I found on the internet - it will work but you would have to adjust your calculations for the effect of the wire.

Not sure if it is his photo, but that is the same picture from Kurt's post:

Which is based on your previous post!

Right off the bat the date is odd and so is the mintmark. Technically it is illegal to possess, but the ANA Money Museum should have a copy of it in its forgeries reference library if it was a cast counterfeit from the 20s and 30s.

I wouldn't even think about checking to see if such an ultra-common date was a fake. Good catch.

Great find, contemporary counterfeit.

Worth more than a real one.
