I still really miss the old coinage. On a Saturday, when we got our pocket money, my mate and I would go to Barclays Bank and get some 5 shilling bags of pennies. (120 old pennies in a 5/- bag, of course)
We'd sit on the town Car Park wall and sort through them. We knew what we were looking for.
When we found a penny that was worth more than face value (eg a good quality one from the 1800's, with Queen Victoria on it, or a rare date, minted at a particular mint, for one of the Edwards or Georges), we'd take it along to the coin/stamp shop and sell it to him. Saleable ones weren't uncommon!
Those were the days! Our current coinage has very little heritage.
