This coin is a "pirate replica", not unlike the one posted by Philadelphian above, although there is one curious "alteration": The date has been changed from 1736 to 1741. Or rather, one of the dates has been changed. The dies for these coins actually had the date on them in two separate places; I assume this was because most of the coins struck using them were "cobs", very crudely struck, and putting the date on twice doubled the probability that a legible date would appear somewhere on the coin.
The date Fuzzy found says "1741". The other date is in the legend on that same side, and says "ANO 1736".
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
