Anybody know coins?

I clean my dad's laundromat for him on a nightly basis and when I dump machines to refill the change machine I come across silver quarters every now and then. Not very often as probably 85% of the quarters there are recycled through the machines non-stop.
I am more likely to find them at my retail job, one guy found 3 in a row in a roll he broke open a few weeks ago- JERK!


Anyways I have a 1965 quarter that I found that when I was dumping them in a bucket, I heard it hit and it was similar to a silver. So I pulled it out and looked at the date and was stumped when it said 1965. It looks like a silver but it's slightly darker and more worn. The edges are almost perfectly smooth but I do see where the notches used to be.

So if you flip a silver quarter, you hear it ringing the whole time it's spinning.
This one, makes no sound at all when flipped.

If you throw a silver quarter onto another silver you hear the ping, this one makes a similar sound but it does not stand out as much as a silver but it also sounds nothing like a regular quarter.

I am trying to find some information on them. I have read there are lead counterfeits and possible 1965 mistakes where a silver blank was stuck in a machine and later fell out while they were doing the 1965 clad quarters.

Anyways, I keep my eyes on these as I sold 4 silver American quarters, 1 Canadian quarter and 1 American dime ($1.25 face) for $48 on ebay. So it is defnitely worth listening for.

I am assuming I have a counterfeit but figured I would ask here before I join some coin forum lol

Possibly dipped in silver, my understanding is no 65 or 66 coins were ever minted in silver. If they somehow had silver to use up, they stamped the coins as 64s in 65 or later.


If you have a scale weigh it, a silver quarter should weigh 6.25 grams clad should weigh 5.67 grams

 

That's what I have gathered. There were some mistake silver blanks that got stamped in 65/later that could have been stuck in a machine or something.

Browsing a coin forum one sold for like $5k in 2006

 

Better find an accurate scale, my guess though from the edge is dipped.

 

Probably, just want to figure it out before I toss/sell it

I have a scale at the laundromat but I think it rounds to nearest 5g

 

Here are more pics. I did join a coin forum too
