The differences between proof and mint state coins also referred to un-circulating are not obvious. This is due to a common thought people have that the terms refer to a grade system. In the real sense, the terms refer to the manufacturing process. However, there are various factors that can be used to tell apart the difference between proof and mint state coins.
Appearance is one of these factors. Proofs have a shiny surface which is mirror like on the flat surface. The raised parts have a matte finishing. Based on detail, attention and quality, these are the finest coin types produced by a mint. The non-circulating have a finishing that is frosty and has a luster like appearance. The difference between non-circulating and those in circulation is the enhancements found in the mint states. These enhancements include after-stamp cleaning.
Another difference is in the production process. Proofs are made by striking the surface using a special minting process. Special polished dies are purposed to engrave the back and the front sides. They are then inspected for flaws and then struck more than once and usually slowly by the striking machine. They get carefully handled, usually by a gloved hand and then packaged in a container to keep them safe from dirt, dust and moisture. The non-circulating are ordinary and their manufacture does not involve any such special procedures.
The amount engaged in the manufacture is another factor used in differentiating them. The non-circulating are manufactured in large amounts and then heaped to be transported and moved to banks. More than one mint makes the non-circulating. The proofs however are produced by just one or few select mints and are produced in small amounts.
Another difference is in how they are packaged. Most modern proof coinage are in sets that are contained in protective plastic cases whereas for most mints coins they are mostly packaged in cellophane i. E. Before 2007. The non-circulating and proofs are also different in the prices they fetch. Proofs fetch higher prices compared to the mints because the time, detail and production costs are also not as much.
There are varied reasons for purchase. Investing, historical archiving and as a hobby are some of the reasons to buy the proofs. Lower coin population result to its rarity and hence increased desirability to a collector. They can also serve as gifts or presents and are also used to remember certain events like World War or a hero.
Lastly, the level of perfection is another factor used to tell them apart. Proofs exhibit perfection. On the other hand, non-circulating may have blemishes from the manufacturing process. Coins are graded based on the level of perfection. The system used for proofs is designated PR or PF. Most of these range from PR 60 to PR 70 with the former being rare almost non-existent. Mint states are graded using MS.
Coins remind us of our heritage and history. Whatever your purpose for purchasing, the most current coin sets can be found at a mint while the older sets are available from a dealer or collector.
