A nice coin with a very interesting provenance Victor. I wonder did the coin come with any old ticket? An exceptional Carausius coin from the same hoard in the British Museum says acquisition in 1958 from BA Seaby: https://www.britishmuseum.org/collection/object/C_1958-0105-1
No, it didn't come with anything except the dealer ticket. That Carausius is magnificent.
