How much does a John Adams golden coin maker cost?

I'm curious about the pricing for a John Adams golden coin maker. Could you provide some insight into how much it typically costs to acquire one of these items? I'm specifically interested in the maker, not just the coin itself, as I'm considering purchasing one for my collection. It would be helpful to know the general range of prices so I can budget accordingly. Do the prices vary significantly depending on factors such as rarity, condition, or demand? I'm eager to learn more about this aspect of numismatics.
