Indeed! A very rare date of modern Great Britain 2 pence that is muled. Here are two examples of the 1983 “Two New Pence” that have the reverse of earlier (through 1981) instead of the usual reverse with “Two Pence”. Pictures to follow of the rare ones as well as the second ordinary type. Both of the former are still sealed in the original 1983 Great Britain Specimen Sets but one must have had a micro-leak in the parking that let an oxidant in. Unfortunately I bought it in an internet auction where the pictures were not clear - else I’d not have bid.
