in the seventies i hear it was in private hands - it does seem unusual the bm does not have one .......but when a coin is that rare.......... Interesting about the 1953 pennies though, they are often found in circulated grade - prob folks who found themselves a bit skint in the late fiffties and broke the 1953 plastic set open , it was for sale with no premium attatched then - unlike the mint of today that charges £12 for a £5 coin and £8 for a £2 coin , basicly double or more than the price of the coin , excessive overchargeing for the packaging IMO
