Proof set coins are a different efrom the average coin you see in your pocket today. A proof coin is specially minted in a process that takes a little longer than the average circulated coin goes through. The dies used in this process are highly polished. Coin proof sets can often demand a much higher price than many rare coins on their own.

The coins are normally pressed two or more times and under a higher amount of pressure than a circulated coin, this is to insure every little detail is perfect. While under this pressure, acid is introduced to the coin to create the satin mirror like finish you will see on a proof coin.

Due to the extra effort put into a proof coin, they are much more desirable in the coin collecting community. Some are perfect examples of the coins that you see every day. These coins are then placed into sets. The sets may be for a particular year or perhaps to commemorate a special event. Most of them are made from precious metals, silver, gold, or even platinum, this will add even more value to the set.

In the United States proof coins have been minted since 1936, every since then the demand for these sets have grown worldwide. The first Proof set sold in 1936 sold for 1.89 today it is valued at over 6000.00 depending on its condition of course. There were only 3,837 sets minted that year. The most valuable of all the proof sets in the United States today is the 1975 set with a dime having no S mint mark on it. This set sold for 7.00 originally and today is worth over 45000.00.The main reason is due to the lacking mint mark on the dime referred to as an error coin.

The most successful proof set every minted in the US is the silver eagle sets they are sought after by collectors all over the world. The demand for these sets continues to grow year after year.
