(4) 1971-D Kennedy Half Dollar Error Coin Silver Planchet

It is possible to find a 40% silver '71 half dollar but I know they are quite rare. The weight of the 40% is 11.5 g with a tolerance of +/- 0.4 g. your coins are within those parameters but having them tested is the only sure fire way to tell. Did you try the tissue test with a common clad half and one of these coins? lay a piece of tissue paper over both coins, if one is actually silver, it will show a considerable lighter color telegraphing through the paper.

This is one which was sold by Heritage a good while ago.

Circulated silver clad coinage can be easily distinguished from its nickel clad counter part by looking at the edge of the coin. The silver cladding tends to darken the exposed copper core and leaves it looking a darker grey color compared to a normal nickel copper clad.

Here is how the tissue test will look.


The Silver will show noticeably lighter.

 

Thank you so much! I will try that. Appreciate it!

 

Thank you!

 

Pam after double checking the weight of a clad Half dollar. These are supposed to weigh 11.34 grams with a tolerance of 0.454 grams. Try the tissue test but the weight and evidence of copper clad on the third side are a give away.

 

Ok this is the first one…..
With a “1972”.

 

With the same “1972”

 

Last one…. I’m exhausted lol!

 

I think they have been plated.

 

Sorry @PamR, IMHO, I don't think their silver...

 

Had to be like 20 plus years ago… my dad’s. But hey no worries. I just tried what they requested. Ty!

 

Thank you. It really does not matter… either way I’m keeping them. Just don’t understand the weight, sound of silver. I worked at a bank for yearsss lol.. maybe my ears are playing tricks. Lol. And eyes. It’s hard to do through photos. If I trusted places around here I would take it in by curiosity but nah! Thanks again!

 

Maybe a stupid question… I look at the chip. I read another test is to scratch it.

 

Ok all figured out. I looked at an old thread on cointalk. Learned a lot just now lol. A 2016 thread. It was a longer conversation. Thank you all. And Seattlite86.

 

Thank you! Figured it out!

 

Wouldn't that add to the weight?
A 40% silver half is at least 11.5? if I recall correctly and 12.5? For 90%.
These weigh in at clad (no silver)

 

I have a 1776-1976-S bicentennial quarter in a slab that is supposed to be silver. People question it.
Tried the tissue paper test with no conclusive results and weighing it don't work either.

 

Yup...

 

I have 64s, 67s etc JFKs and Morgan’s etc but I guess I was thinking it was 40% it would show differently. But after reading more I understand clad verses silver. Ty!
