Thanks Ross. That's what I expected you to say.
When
Bendall first noted
type 24 in
his 1984 article, there were two references: Barber and private
collection. When he published
PCPC in 1988, he included five coins in the plates, and one of them was
type 24. This suggests that the "private
collection" coin he referred to in 1984 might be the same coin he published in
PCPC. Curiously, the
PCPC coin is a
plated fouree (and described as such). I would be interested to take a closer look at the Barber coin, but as far as I know the
collection is unpublished.
Naumann has sold a couple of
type 24 hyperpyra in 2019, one in
Auction 75 (Lot 870) and one in
Auction 79 (Lot 819). Both have sufficiently legible legends to confirm the
attribution to Andronicus II-III. Here is 75/870:
