Nice find, but, there are still too many 1967 quarters still in circulation. No added value, unless at least uncirculated, or even mint state. Mintage for the 1967 quarter was over 1.5 billion.
What @Legomaster1 said. It's pretty decent for a 52-year old coin found in circulation, and as such, would be a keeper if you needed it to fill a hole in your album, but technically it is still a "spender" worth 25 cents. Not bad looking, though.
What @Legomaster1 & @lordmarcovan said. What does the reverse look like? The obverse is nice enough, a keeper , I would think.
I once found a 1967 like that in change back at the post office after shipping out one of my items. A keeper, but there's a lot of those 67's floating around. Agree with Legomaster
