I spotted this King George III Maundy Set on the Internet and purchased it. It's part of my studies of the coinage during George III's reign. There was a severe shortage of coins in England during this period. The factory owners didn't have any money to pay their employees. The Spink guide lists prices for the Maundy coins in the circulated grades. Many of these coins were spent, not collected. The trouble was, there were not enough of them to put a dent in the coin shortage. People called them "wire money" because they were so thin. The temporary solution was the Condor tokens. Here is one of the first Condor tokens, the Parys Mine Druid half penny token.
Nice finds! I have to correct on one point though - "Wire Money" refers only to the Maundy issue of 1792, which had a very different, almost italic, form of the numbers on the reverse. Here is my example of the fourpence from that year: Oh - and I'm sure just a typo, but your set is 1786 not 1768. None were released in 1768.
Great looking Maundy set up there! Here's my George III Kettle token, not sure it's a real Kettle but I think it is!
