Looks like a Business strike. I wouldn't know an SMS if it bit me in the behind! Beautiful Toning though.
I recall seeing more SMS examples with toning than business strikes (but that alone is not enough to make a call). Also the SMS tends to be more prooflike but then toning can make that less evident. One more possible thing to look for are scattered small hits. Business strikes are more likely to have them from being handled less carefully than the SMS examples. Making a guess, I would say SMS here ...with some room for doubting my own call
Yeah I know... I lean to the rims more than the surfaces, It's a hell of a strike, but the rims are paper thin. The striated planchet, could be a thin clad layer. It has me a little puzzled I will check your comments. Thanks.
Does the toning cause those striations or just accent die polish lines? I'm clueless on some of this stuff.
There is a roller machine that flattens the planchets to the proper thickness before they are punched from the strips into planchets. If the metal is stretched, or the rollers keep moving but the bed feeding the strip doesn't, It causes striated lines that the mint thought they could strike away. Most always these heavily striated coins cause come wild toning. Here is a 2020 Roosevelt.
