If proof coins are legal tender and can be spent, how do you grade a proof coin that has been circulated?
Proof isn’t a grade. Instead it is a designation for a specific form of coin intended for collectors and made by a special process that gives it a different appearance than a regular circulating coin. Proof coins have their own grades, designated at PF-60 to PF-70. They roughly match the MS-60 to MS-70 (Mint State) grades for circulating coins or business strikes, as they are often called. A proof with wear would be considered an impaired proof.

Why do early Mexican and South American coins have three or four letter mintmarks?
The letters designate two things. The mintmark is one, shown by either one or two letters. The other one or two letters are the assayer’s initials. In the early mints, the assayer’s job was important, and dangerous. A coin found with an assayer’s initials that was underweight or had the wrong mix for the alloy could cost him his life.
What is the early history of the two-headed eagle on Russian and Austrian coins?
