Comparison of a Proof and Non-proof Coin

In this post I shall use the 1972 Eagle Coin as an example. For Singapore non-proof coins, they usually come in a red coin holder and is not encapsulated. For proof coins, they come with a certificate of authenticity(apart from the 1972 coin, apparently the mint did not issue a COA for this proof coin), encapsulated and with a box. The mintage for proof coins are much lesser than the non-proof coins. (For 1972 Eagle, non proof mintage: 80,000. proof mintage: 3000) Another difference would be the finishing, a proof coin has a much intricate and mirror like finish.
