Yes, it certainly seems to be the
McAlee plate coin. The little
flan flaw at 4h on the
obverse is distinctive, and all other features and centering seem a match to my eye.
But wait, there is more. I think your coin was
McAlee's own coin, and the only example he lists. Here is
his complete catalog entry:
380. "Holy Year" 3 ( of
Vespasian ) = A.D. 70/71 Same as no. 379, but
obverse legend from upper r., which ends in squared "C".
Prieur 141;
RPC 2, 1968; BN; Empire 3, 5 May 1985, 186 = MC. (
Rare )
MC is
McAlee's notation for My
Collection, so I think you don't just have a plate coin, but a
McAlee provenance as well. Plus,
his note that he acquired it in 1985 from Empire Coins.
