Dave, I'm pretty sure I saw posted that geordiefred lives England. Better chances of finding older coins and relics than either you in Pa, or myself in Jersey.
Last week I did find my oldest coin - a chinese coin from the Emperor HSUAN TSUNG AD 1821-1850 era. S-1512, "BOO CIOWAN" (Board of Revenue mint). The Manchu mint name translates to Pao-Ch'uan, or "The Fountain head of the Currency". Unfortunately there are not individual years, so I can't tell what year specifically it was minted.. I thought it was a rusty washer. It doesn't look as good as these attachments...
