The coin is unlikely to be silver because the only silver State quarters were minted* in San Francisco and sold in special Prestige proof sets. If the coin doesn't display a copper edge it should be examined in person by a numismatic expert, but my guess is that it will turn out to be a plated copper-nickel coin rather than an actual silver quarter.
(*) To set things straight, coins are said to be "minted" or "struck". Printing refers to paper and ink.
The 1999-S silver proof quarters are about $8.00.
....25 cents just like any other post-1965 non-proof quarter. State quarters are not rare or valuable unless they are proof or have some error.
If the coin is a silver proof still in collectible condition, retail value is about $8.00

Neither the US nor Canada have struck circulating silver coins since the 1960s. If your coin is a collector's issue such as a US Prestige Proof, please post a new, separate question with more details.

The 1999-S silver proof quarters are about $8.00.
It's likely to be valued just for the silver, about $5.00. If I understand this question, someone signed 1999 silver proof quarter?
Look at the coin again. 1992 was the first year for modern silver proof Washington quarters.
No US quarters dated 1966 are silver. The only US quarters struck in silver are dated 1964 or before with the exception of silver proof sets (most proof sets are -not- silver and silver proof sets are marked as silver) but those are dated from 1992-present.
The 14-piece silver proof set is currently valued at $44.00. Issue price was $56.96. A 5-piece Silver Quarter proof set is $38.00. Issue price for this set was $32.95.
