Unlike bullion coins, the value of numismatic coins is not based on the amount of gold contained in the coin (the gold content) but solely on the price that a willing buyer will pay for the coin in an open competitive bid system.
These “rare” coins are collected and valued for their scarcity, individual beauty, age and condition.
Semi-numismatic coins are those that are either numismatic coins of a low grade or fairly common coins that still have some collector’s value. The primary value of these coins comes from the gold content, not the collector’s value. Semi-numismatic are less expensive than true numismatic coins, but they do carry a higher “premium” than regular bullion coins because they are in demand among some collectors. The higher premium also results from the limited supply of these coins, as they are no longer produced. These are the same coins that in higher uncirculated grades are called numismatic, “slabbed” or graded coins.
