Heck I am only just getting round to listing my own collection, let alone the spares!
There are boxes of Pennies labelled up - one for pre-1911, the other for 1911 to 1967. There is another for Halfpennies, another for farthings, another for Threepences. There are trays of hammered and Roman, trays and boxes of assorted foreign. Quite a few shillings and some great 20th century florins and halfcrowns, but much lower volumes in the bigger stuff as that sell more easily at markets.
Best is if you have an excuse to come down this way, let me know and we can arrange to meet outside the market days - that way we can explore the boxes and chat without the pressure of time or customers. I might even let you look at the collection!
