Numismatic coins are perhaps best defined as ‘older coins in limited supply’. Unlike modern bullion coins, which can be produced in unlimited mintages, the production run of older coins is of course a known quantity and availability is limited. These coins are often aesthetically and historically appealing, and they’re commonly graded by third-party entities to establish a ranking of quality, all of which allows a market to arise in which numismatic coins can be worth more than their weight in gold. These coins can have considerable value, as well as giving great pleasure as objects of beauty.
