Collectors disire them more ,and depends what coin it is for the pricing,depends on varieties,errors the cost of a coin,sometimes don't need errors or varieties,just a very clean stamped coin,and depends on mintage as well,how many were made
OK got it. Now you said mintage and I'm seeing a lot of that word. What does that mean? I'm sorry if I am pestering you. You can tell me to stop asking questions if you want. I won't be offended.
Oh no I love answering questions,I don't know all the answer but would let you know,mintage is the amount of coins made each year,but some years some coins they didn't make a lot,example 1940 penny ,3 coins,mint marks-p,d,s,where they were made,1940 p they made (586,810,000)-1940d (81,390,00)-1940s (112,940,000) P-Pittsburgh D-Denver S-San Francisco
