The last Standing Liberty quarters were minted in 1930, and all were made of 90% silver. It would be essentially impossible to find any in circulation today unless someone accidentally spent one from a collection, or it was "dropped" as part of an effort by a coin collector or coin agency to generate interest in collecting.
No.
Generally any US quarters made before 1965 are collectible because of their silver content. Any proof(S mintmark) and uncirculated quarters are also collectible.
Yes, they are made of 90% silver.
Do you mean 1,997 quarters, or quarters from 1997, LOL? In any case they're worth 25¢ each. Out of curiosity, because these are readily available in pocket change, what made you suspect they are valuable?
The "M" is actually the designer's initials, the mintmark (if any) is found on the other edge on the left. No 1929 Standing Liberty Quarters are key dates, but high grade standing liberty quarters are worth a premium regardless of date. However, if your coin is worn, it is really only worth about $6-7 in silver melt.
Modern silver quarters are only made for sale in special "Prestige" proof sets sold to collectors. They're made of the same 90% silver / 10% copper alloy that was used for circulating quarters before 1965. Circulating quarters dated 1965 and later are made of nickel and copper, and do not contain any silver.
There are four quarters of a mile in a mile. There are four quarters in any whole.
