It sounds like you may have a significant mint error coin. Sounds like a flip-over double strike, possibly on a dime or quarter planchet. If genuine, it could be worth several hundred dollars. I suggest you check out Mike Byers' website to see if he has anything like it there : http://mikebyers.com Then contact him and send him magnified pictures of both sides of the coin, AND a picture of the outside edge. Good Luck!
Do you mean a quarter DOLLAR? Quarter eagles were not issued in 1968. And could you describe "double 'stamped"" ? (note the term is actually "struck" in coin jargon).
This is a rare misstruck error and is worth up to $90.00 according to condition.

This type of quarter was designed by Hermon A. MacNeil. The M is MacNeil's initial.
August 1, 2009 The US Mint has not issued a quarter with an "M" stamped on it. Probably what you have is a quarter that someone has put their initial on or marked it for some reason. With such a mark it has no numismatic value but is worth $2.52 for the silver it contains.
30 cents; 25 for the quarter part, 5 for the nickel part.
Usually, only 25 cents. Unless it has any odd features like only one side stamped or double stamped ect...
The coin needs to be seen for an assessment, take it to a coin dealer.
Unfortunately regardless of the grade of the coin, the letters stamped on it reduced the value to the silver only, about $3.00
ten thousands dollars
