Are these coins artificially toned? They look nice, but I noticed that just about every single one of his morgans are toned the exact same way. http://coins.search.ebay.com/_Morgan-1878-1921_W0QQcatrefZC12QQfsooZ1QQfsopZ1QQsacatZ39464QQsassZmidwesttrustcoinsandcollectablesQQsbrsrtZd
They could possibly be all from a single hoard or something....If they were all stored the same way, I suppose it's possible they would all tone the same....
If I had to guess, I would say that all of those coins had been housed together in the same album, being that they seem to be a series of date/mintmarks, and the toning all looks like the kind you get from an album.
I agree with everyone else. Look like these are all from the same hoard as well all stored the same way if not all together in the same place.
