25 cents in anything below Mint State. Even in the lower Mint State grades, they're only worth a dollar or two. 1964 and earlier coins are a different story, since they're silver.
I didn't see any provocation at all. Maybe you lashed out because you didn't get the answer you wanted?
My initial post read simply, "25 cents", because in literal fact, that's what practically every 1965 quarter (of unspecified grade) IS worth, unless they're Gem BU. But @Pkrplyr thought I was being sarcastic, and called me a rude name one often calls a sarcastic person. Hint: when you're new on a web forum, it maybe isn't very good form to come in asking an extremely vague question and then lash out at the person who answers it with the literal truth. Particularly if you start calling that person names and that person happens to be one of the forum's moderators. Not the best entrance, but we'll forget about that. Welcome anyway.
In some circles, mostly people who are trying to fill a dansco album you can get more than face value for some things. But then you have to consider mailing the thing, packaging costs, etc and it ends up not worth it for most casual sellers. if you sell a bundle of coins to album filler types you could do better than break even. But without a good, bright, non-fuzzy picture, no one really knows what condition your quarter is in. You don't even mention that it's a US quarter! It's like, I'm selling a 1965 car ... how much is it worth ? Can't answer it can you? The first question is ... what kind of car, is it in pristine condition, or has it been stripped and is a rusted shell or something in between ? The value would of course vary greatly. Same with coins in a way.
I'm a 1965 model myself, but not in very good grade. Somewhat worn, so probably only worth face value. I dunno. You'd have to ask Ladymarcovan about that.
For instance, this 1965 SMS BU (BU meaning it looks Brand spanking new) sold for $1.19 on eBay. Then what .. take 10% off of that .. you now have $1.43, then if you priced shipping to include all the packaging cost and at least broke even on total shipping & handling. Now how much time did you just spend to do all of that for a max $1.18 profit assuming in perfect condition ?? https://www.ebay.com/itm/1965-PROOF-LIKE-CH-BU-Special-Mint-Set-Washington-Quarter-SMS-Coin-19-NO-RESERVE-/372346616471?hash=item56b1967a97:g:AagAAOSwQctbMCku&nma=true&si=tg0DxIPVVqWD9G0UHqh6BUrzi4g%3D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557 BUT, if yours is in less condition and a regular quarter (which it probably is) then it's value significantly decreases. It's worth at least a quarter though right ?
1965 are very common, they minted TONS of quarters in 65 66 67 they are worth a quarter. Any 1965 you get in change is worth a quarter. Almost 2 billion 1965's almost a billion 1966's and 1.5 billion 1967's. That's why you still see a lot of them today. It's just a quarter. It would be (almost) impossible to get a mint state 1965 quarter from circulation.
