Hello all

Posting the first of my interesting USA coins for general comments and discussion! This is the oldest silver one. Pretty beaten up!

This should be a common 1900-O Morgan dollar from what I researched. I don't think this can be a CC/O despite the heavy wear.
Is my identification correct?

From looking online (found a nice Mint Grade chart) it should probably be a grade between AG3 to G5? What do you think?





This silver dollar was passed down since the 50ies when it probably emigrated. Not sure if it was cleaned before. Strange looking corrosion/patina on the left obverse.
How would you conserve it, if anything at all? Water & acetone cycles? Something for the green oxidation or whatever is going on with the obverse?

Thanks all!

This is a details coin given the damage in the left obverse field and into the rims. No conservation is going to make this coin grade straight. I would keep it as a historical artifact connected to your family since the 50s. I know the U.S. wild west has been a popular topic in Italy for a long time. When I was a kid I had a book called "Morte Della Neve" set in the Sierras in the Wild West. Thanks for sharing an example of a coin that emigrated to the old world.

to the CCF.

Thank you numismatic student for pointing out "details coins". Didn't know about them!
Would this be in the AG DETAILS realm or G DETAILS realm (or more or less)?

It's interesting how the P on the obverse is basically evenly etched into the metal.. how could this happen?
Anyone wants to take a guess?

By the way, my will to do something in the conservation department is just to preserve it.
Wonder if whatever ate the observe is still at work there? Obverse and rim is pretty gunky.

Joe you can try some pure acetone and then rinse with water and pat dry to see if it removes and surface grime.
Other than that I would not do anything as it will only damage the coin further

I believe this would be an AG details coin..

Based on Photograde I'd give it G4 Details. It has mostly full rims all around showing some denticles. AG shows no rims left. Borderline though.

Too far gone, just a bullion coin.

Thanks to all!

By the way, here's a detail of the P completely eaten up. Anyone want to guess how did this happen? Or what that bubbly kind of gunk on the obverse is?

Nice piece of history here, I would leave it - but do give it a goo long soak in Acetone (NOT fingernail polish remover)
