An absolutely_indifferent strike insufficient to erase planchet striations, I think. These were struck in astounding quantity by the Mint - I think twice the number of any individual issue they'd ever attempted before - and this one, from the ghosting, looks to be a very old die which they may have been attempting to prolong to the bitter end of its' life. Perhaps by way of deliberately researching that limit.
I agree- very pronounced roller marks from the metal strip being pulled through the draw station prior to planchets being punched. The worn dies have produced some very attractive swirly luster.
Also severe PIDT as SuperDave was alluding to. Progressive Indirect Die Transfer - fairly common in 52s. If I remember the #s offhand (Flynn and Zack is upstairs), they minted around 18M using 103 or 104 dies. Call it 175K strikes per die. Hardened steel smacks hardened steel with a tiny strip of soft silver between. Again and again and again... Which causes obverse elements to work themselves into the reverse (largely hidden by the reverse design) and reverse elements to work themselves into the obverse (visible as the faint C that appears outside of the star).
Nice 3 Cent silver pieces! Personally I like the roller marks and the ghosting. Makes the coin more interesting IMO.
