I have a 1966, 1975, and 1978 dime with no mint mark...and I'm hopeful.

Good to know. Thanks.

How can you tell? If its not a old proof that some edited open and used it because he did not know any better how can you tell for sure please?
I have one that is real shinny.
I am new to this aslo and i'm enjoying the hunt any help will be appreciated.

 

It's hard to describe the look of a proof in just words. Once you see a few you will be able to tell the difference. You could go to ebay and look at some images. It can be a great tool to learn from. Welcome to CT.

 

I took this image from ebay of a proof.

 

When I was working in San Diego, I used to go to the bank every 2 weeks and deposit my paycheck. While there, I would take any Ike dollars they had (this was in the late 70's). One day going through them, one shined up at me...the only proof I ever found in circ. Most proof coins have mirror-like backgrounds (with some exceptions) and the strike is super sharp. There are indicators on many.

 

Maybe this article I wrote about this subject will help. As ldhair mentioned, using words to teach what a proof coin looks like is like trying to smell the color 9. Since that is the case the article i wrote is a bit lengthy. I hope it helps.

Thank you.

 

I love the aroma of number 9.

 

this is my coin who is to say that someone did not open a proof and put one of these dimes in to circulation without knowing any better ? coin not clean at all it was in my change bin, i know that polishing a coin is bad..

if you look closely you can see the the we in got we trust is not on the coin all the way as is should be . might be hard to see from the pics

 

thx

 

If I am not mistaken, in 1975 the proof sets were made in San Francisco, so the dime should bear an "s" mint mark to be a proof.

 

I belive that the s mark was mistakenly not put on a certain amount of coins witch is what makes the valuable.

 

Good luck

 

thx

Looks like an average worn down '75-P Dime..... not a Proof

 

Thx for the help the hunt will continue

 

I have found a 1975 roosevelt dime with no s. Is it rare.

 

Do you have an image? They were made without an S and with a D mintmark. These are not rare. There were proofs made without an S that are rare. With an image we can probably tell if what you have is a proof.
