Silver Proof Statehood Quarter

I found a 1999 Connecticut state quarter that I believe is a Silver Proof. I have a 2011 blackbook price guide for US coins. In the book it shows that this coin was made a Silver proof only with a S mint mark and the coin I have has a D mint mark.

Can anyone help me out a little with this one? Thanks alot

What exactly makes you think it is silver?

 

Because there is no copper around the edge

 

Silver quarters are minted at the San Fran mint. Why would feel that a Denver coin was a proof? Now it could be that the coin in question is proof like, but in reality it couldn't be a proof. Post a pic for all to see....

 

Also, it could be that the inner copper core is missing. What is the weight of the coin? Clad quarters weigh 5.67 grams. Silver quarters weigh 6.25 grams.

 

I read on this forum an easy to tell silver vs. clad: hold a piece of tissue paper over the coin, a silver will show up white, where a clad will be grey in color, looking at the coin through the tissue.

 

I cant weigh it, dont have a scale will try to post some pics the. Standby

 

Is the coin thinner than usual?

 

I hope these help they're the best I can do thanks again

 

No its the size of a normal quarter

 

The coin also is like a mirror I can actually see myself in it

 

Well, I'm stymied, except for the fact that judging from your pics that coin does not look like a proof.

 

Is that a scan?

 

Tissue Test

 

does it sound like silver when you flip the coin or tap it... does it make that nice silver ring tone?

 

yea its a scan. if its not a proof what is it, its the 1st and only one like it that ive seen

 

It just looks like a circulated proof. They do end up in circulation. I found a 2007-S George Washington presidential golden dollar a couple months back in change. Collectors may dump them in circulation if they crack out a proof set and the coins are problem or inferior grades, but collectors are not likely to spend a silver quarter so readily. There are many, many ways a proof coin can end up in circulation.

 

I just tried this and now I am even more confused. it sounds exactly like a regular copper clad quarter BUT as you can see in the pics its not clad. What else could it be?

 

plated - HSN sold platinum plated quarters.

 

never heard of a Platinum plated quarter, im gonna look more into this
