this is todays star find from the flea market, an 1858 flying eagle cent, all for the princely sum of £3.50
The best I ever did was at York Race Course flea market. I bought a coffee jar of coins from an antique dealer for £10, it contained lots of 17th century Dutch silver Duits But the Star Prize was a Liberty Security Token, which I sold on eBay a couple of years back for $2400 :smile
