Treasure Coins
What pirate or wench wouldn't like to have a few treasure coins in their possessions.  They be a bit harder to come by now a days, but they can still be had.  Most of the coins to be had are coins the come from shipwrecks.  It cost a lot to get 200 - 300 year old coins from the bottom of the ocean, so they be costing more than just the weight of silver or gold contained in them.  They be graded by the condition they be in.  Early coin be hand made of irregular shapes called cobs, not until 1790 did coins become minted in perfectly round in shape with a edge. Most coins will come with a Certificate of Authenticity which gives the history of that coin.
