American Eagle Coin?

Question

What is the difference between a American Eagle Silver Dollar Coin PROOF and a American Eagle Silver Dollar Coin Regular issue Uncirculated

Answer 1

Uncirculated
The word "uncirculated" means exactly what it says, the coin has not been in circulation, however "ordinary" uncirculated coins often have bagmarks, edge knocks and other small scuffs and imperfections. Uncirculated "specimen" coins issued specially for collectors are often more carefully produced and handled, so they may be better than ordinary coins mass produced for circulation, but may still have some small imperfections.

Proof
Proof coins are specially produced to a much higher standard of finish. Originally, proofs were intended as pre-production samples. As a printer would produce a small number of "proof" copies for checking and approval, so a mint would produce proofs for approval by the mintmaster, the monarch, and for other purposes. When coin collecting began to become popular about two centuries ago, a larger number of proofs were sometimes made for sale to collectors. This has developed enormously in the past few decades, and most countries, but not all, produce proof coin and sets every year or on special occasions.
