1965 Washington Quarter

Dear Sunny, you do 'it well. Now please look at the head of the president and In good we trust. Do are they same? Answer NO. So you are in a front of two coins with same year, but two different design. Till 1965 the coins was struck in silver, then the mint move to the clad coins which are core cooper and clad with nickel. So the coins you have the left it is the die use in 1965 and the right it is the die use in 1964 and before.

Please analize the heads design, the linnes of the nose, and also the letters. Please come back with your conclusions and then I show more. Do not forgot to look parallel at the hairs.

Before to state this I will look of the melting temperature.

The clad it is an Ni-Cu alloy in order to bond on the core cooper. Due to the 2.-2.8 tone forces apply, the clad will made molecular bond.

the cooper will melt faster then nickel. Here we have the rim which "apparently" was heat and made a bulb. This will happened only if one of the materials will melt. the sides are correct, so no material was melt.

if the core was melt the nickel will start to shrink because the melting point on the cooper coincide with the begin of nickel melting.

I know is like to be contradicted, but I say: this it is physics, chemistry and metallurgical science.

My point was not heat or not, was the variety of the compare the two coins the Miss posted.

@ Sunny. About the value I have no clue. I do not say it is an 1964 coin, just is an 1965 coin struck with the Observe of the 1964 which was in use from 1945. In 1965 the hub Observe hub was rework in the way to be compatible with the new coin composition. Was already documented that some 1964 Observe Dies was use for the production of the 1965. Those coins with those observe we say it is transitory coins. Are not to many on the market. Another transitory coin for 1965 it is coins struck on Silver planchet, but it is not your case.

Before to grad, I will try to see the prices obtain by the auctions. The best place it is Heritage. Think that the price of the coin on sale basic must be at least 2x of all costs. If you do not find just mail me and I will assist you on this diligences.

Later this afternoon I will post here the photos from my book of the 1945-1964 Observe Die and the 1965-1973 Observe Die.

PS. I am jealous, Your 1964 die coin is in better grade then I have.

Look at the head large. The 1945-1964 is a little bit thin

Like promise Miss,. here are the picture of clear dies design. I am glad you learn something that many collectors do not know or observe.



And to complete, the 1965 the relief il lower in order to accommodate new production of the clad coins.

Please enjoy this new field you come in.

The book will be on printing in December and it is the first in series of four. First will be Quarters 1932 to 1999 then JFK followed by Nickels and Dimes. Touch the design varieties Observe and Reverse. Is ready for printing but I need to resolve some legal problems before. Me I say problems, but are not problems we talk about permission for example to can attach for each year of strike an small index of Cuds, DDO and DDR as are listed on VV, Cuds etc. I do not touch the DD because I do not study them, just listed. So I need the permission from different owners of those examples to be able to list. My attorneys work on.

I emphasis on hub design. The name will be Quarters design varieties and will be available for CCF members trough the forum at discount and some profit for the forum.

I agree with Sil, if there is a dent and corresponding bump on other side I would have to say it is still PMD but damage by impact not heat. If this information had been given out at the beginning, troubleshooting would have been easier and quicker.
as for the other stuff said by Sil, I still have a lot to learn on this hubbing stuff.
