1963 Washington quarter proof toning?
I bought this raw proof a while back for really cheap I thought it was pretty amazing even if artificially toned. I had a few other rainbow toned quarters that I sent in but they were business strike not proofs. Come to find out the business strike ones were real I became intrigued by this one. There are several proofs on CoinFacts that have very colorful/similar toning I just don’t deal in quarters hardly ever… Any thoughts on this artificial vs natural toning? Seems too good to be true but would like to hear peoples thoughts. The surfaces are still fully reflective there’s no cloudiness like on proof Eisenhower dollars from those government sets. If you want more pictures just ask, thanks for any help!
