Is a 1967 US quarter, with no mint mark, really worth so much? I've seen them for sale anywhere from
$3.00 - $2000.00. Should I be looking for coins (US) with no mint mark?

All US coins between 1965-67 had no mint marks so you won’t find one with one.
Where did you get that pricing from?

ebay.
Thank you for the reply. Very helpful. I'm new to the coin world so it's all trial and error.

And outside 65-67, as explained above, for almost all US coinage with no m intmark means it was from the Philadelphia mint .... D, S, O, CC had MM's for Denver, San Fran, NOLA, and Carson City.
