so ICG misgraded that 17 for a 16 ?
Yet your telling me that's who you would send a dateless 16 to ?
what if they claim its a 17 ?
Also what a POOR graded 16 worth ?
Sure they are on ebay does anyone purchase them?
The grade books show G3 readable date $2900
Most other coins the value drops a huge amount as the grade falls
with a partial date by 1/2 value usually Average with a worn first or last digit , then agian by half when down Fair with to 2 readable digits , But no readable digits would be Poor esp if the head,shield are worn so bad you cant make out its a 16 with out a huge forensic scientific effort to decipher its details

Thunderchops is absolutely correct. The ICG coin is not a 1916, it is a 1917. I have seen this seller post this coin in the past, and it have informed both him and ebay, all to no avail. I think there is an earlier thread on here about it.
Occassionally they either are misidentified, or its possible that the slab has been tampered with or is counterfeit. I have used ANACS to send in 2 dateless 16s, and they correctly identified them both as 1916 and graded them FR02. I kept one and sold the other for $1100 as an ebay BIN.
Anyways, dateless 16s can be identified and they do have substantial value. PR01s go from $600-$800, so they are definitely worth finding and identifying.

I'll let you in a a way to get a date on the silver coins.
I tried it on a worn SLQ x92x when I was done the date was readable to a 1922
Start with one of your later date SLQ that you dont care about ,
I am no scientist so I cant explain it in detail other then basic instructions.
What i'll try to explain is metal warping/seperation/toning all in one.
Metal expands and contracts with hot or cold.
Its not a lot to be seen with the naked eye but it does.
When the die comes in contact with the coin during minting the lower areas on the coin have been minted with more force then the highr areas, or more metal has been compressed mashed down.
The higher area we want to focus on is the date, in the date the letters have been minted with little pressure but the fields around them have been compressed around the date aka outline.
the coin is 90% silver , 10% copper. The copper will darken and oxidize.
The process of heating and freezing over and over will cuase a slight oxidation and discoloring of the copper inside the coin.What will appear is a slight darkining of the copper fields around the old date It will kind of leave a mirror shadow around the old date.
The date will be lighter and the fields around it darker. Making a date some what reappear.
Take the SLQ and expose it to butane lighter fluid hold it with some tongs. Spray the coin with fluid till it ices over. Then dunk into hot boiling water, wait a few seconds. Freeze agian , then dip inside out water
freeze dip .
It might take 10-20-30 times.It will help the coins metals warp from with in forcing the high point in the dates exapnd outwards
Then take the quarter on a ceramic plate place it inside the over around 350 deg for 30 minutes this will further cuase the copper to darken.
what will happen is the coin will darking and the date should appear in a ghostly witish look, You will prob have to turn the coin in the light back and forth and the date might be really faint.
Also with the expansion contraction you might get the digits to slightly reraise off the surface , I'm talking 100th's of mm here just enough to catch the light to reflect a date.
I had so/so sucess with this , hopefully someone with a scientific background will red this and explain it better

Great idea! You should run some more experiments and post pictures of the results.
