Coin history
Low mintage does not always mean valuable
Mintage is the number of coins struck for a given year and mint. Low mintage can make a coin scarcer, but demand and survival rates matter just as much.
Some low-mintage coins were saved in large numbers, which keeps prices modest. Others with higher mintages are very rare in top condition.
Use mintage as one clue, and check the coin's grade, demand and recent sales before deciding what it is worth.
