Nice and
rare coin, that I know well!
Presumably you got it from
CNG E411, 13
Dec. 2017, lot 406? Their description calls it a
Banti plate coin, and also gives two other provenances:
Ex R. D. Frederick
Collection (Classical Numismatic Group Electronic
Auction 290, 7 November 2012), lot 410;
Thomas Olive
Mabbott Collection (
Part V, Hans M. F.
Schulman, 7 July 1970), lot 485.
Mabbott was a famous collector, so a
provenance worth recording!
I believe the dealer
Christian Blom bought the coin at that 1970
Schulman sale; soon thereafter, I bought it from Blom.
However this coin was left over when I sold the
Severan and later coins from my first
collection to the BM in 1991, since the BM already
had two examples of it (
BMC p. 469, 211-2). Eventually I sold it to
Harlan Berk, who put it in
his Buy or Bid Sale 129, 24 Oct. 2002, lot 311, whence it was presumably purchased by R.D. Frederick, whose
collection CNG sold in 2012.
Unfortunately my copy of
Banti is packed away in a box, so I can't confirm that he illustrates this coin. If so (and there is certainly no reason to doubt CNG's word!), presumably
Banti just reproduces the photo from the 1970 Hans
Schulman sale.
My note on this
sestertius from
Berk 129 of 2002:
"
Rare variant. This
reverse type was common with
obverse legend IVLIA
AVGVSTA late in the reign of
Septimius Severus, but was only continued in a single
reverse die, that of our coin, with the new
PIA FELIX legend of the joint reign of
Caracalla and
Geta."
