The 84 -O is the closest to being proof like, but it isn't. It would grade a solid 63. Perhaps, it might push for a 64. If you want to educate yourself on proof like coins, study the 81-S. Nearly all the 81-S's are spectacular and have proof-like surfaces. Finding one without is more the exception. They are the one Morgan that I can't seem to say no to. Despite have multiples specimens, I keep adding another whenever one meets my expectations.
