I think your math is a bit out. ONE bag of old Pennies weighs 9K and contains 1,200 Pennies - that's £1,200 pounds by doing the current auction - somewhat more than weighing in 9K of not totally pure copper
- even at todays over-inflated metals prices.
I won't be bollocked for defacing coins of the realm if I sell them 'as is' _or_ melt them down - they are no longer coins of the realm.
I am currently selling 2003 2p coins for £10 each which have legally been (quite seriously) tampered with, as you know, and with the full warrant of the Treasury as granted to the Magic Circle. I'll soon be doing something similar with the other coins, especially the sixpences
- and selling them for £10 each too - making a bag worth somewhat over Ten Thousand Pounds (not that I intend trying to sell them all - but still better than melting them down).
