What pirate or wench wouldn't like to have a few treasure coins in their possession? They be a bit harder to come by now a days, but they can still be had. Most of the coins to be had come from shipwrecks. It costs 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 the silver or gold contained in them. They be graded by the condition they be in. Early coins be hand made n' of irregular shape n' were called cobs, not until 1790 did coins become minted perfectly round in shape with a edge. Most coins will come with a Certificate of Authenticity which gives the history of that coin.
