1965 Special Mint Set

Would be even better if it was a clad! and for the record, in 1965 the US Mint was making Clad coinage, just not the halves. It is conceivable that one could have been struck on a clad planchet but highly unlikely.

I am with Doug, you can't see a copper stripe on a 40% clad half because the core isn't pure copper!

Right, they were striking clad coinage in 1965, but not halves. So, they didn't have clad planchets for halves in 1965. If it was struck on a clad planchet...it would have to be a quarter or dime planchet which would be obviously small.

That said, to my knowledge I have never seen a 40% half with obvious copper showing. I just looked at a whole roll of them and none had it.

 

um, no, Doug. It doesn't. The inner core is also an alloy of .791 copper and .209 silver - also an alloy and not showing ANY pure copper stripe because there is no pure copper component in the planchet.

 

Mike Noodle is right.

The 100% copper core didn't come out until 1971.

Additionally, no "coin core" is completely "wrapped" in cladding since coins are gang punched out of strips of clad material.

I'm quite surprised that Doug even made that statement regarding 40% Silver Kennedy's.

 

Hmm, just checked again and I can see the core. It is less red than a 71 half because the core is part silver.

It must be Doug is so old, his eye sight was already gone when these 65's came out.

 

that quarter clearly needs to be sent in for authentication because with the large copper stripe that you have pictured, I will go out on a limb and say that it is clearly NOT on the correct planchet.

There are no copper stripes on 40% clad halves, quarters or dollars.

 

There is a line of separation between the alloys of all 40% planchets. It can be extremely difficult to see, but it is there. Take this info from someone who has found nearly 500 40% halves in circulation in the past year; me.

 

that may be true, but that seperation is not, nor will it ever be seen as a copper stripe

 

On well-circulated examples, it does turn a color that is just slightly off of what a Cupro-Nickel planchet displays. I've got plenty of examples if you really want to see... Just give me a day.

 

The copper-nickel planchet will weight .2 of a gram less than a 40% Silver planchet while a 90% Silver planchet will weight nearly a full gram more than either of the clads. A simple weight comparison should be the first step.

As for the alloy core showing on these planchets, I have seen what appears to be a different colored edge and I've also seen whats appears to be a solid white edge of which both scenarios exist with coppernickel planchets as well.

However, a 100% copper core would always have a bright copper edge.

90% Silver Weight = 12.5 grams (+/-)
40% Silver Weight = 11.5 grams (+/-)
Cn Clad weight = 11.3 grams (+/-)

 

There all so a 1967 non SMS issued to my grand mother owned a bank her Dad opened. she would get me Morgan& Peace roll and anything to keep me from hanging out . the bank in Catskill NY caller Tanners Bank till she owned 1906- 1980.I have 1 roll and few lose one here a photo of it & regular SMS

 

Sorry to bump this but a year and a half later I finally come across a scale.

Drum roll...........................

Both coins weigh exactly the same. 11.5 grams

 

Darn those scales!
