[theshoenlebens]

Need some help guys.I have an 1974 proff set in the case and I'm not sure if it is 40%?? Are all 1974s ikes silver?? It has the eagle and apolloon back

You will probably have to weigh it.

Might come down to it but I really don't want to break the plastic case to get it out. Probably leave it in there as-is anyways no matter what the composition is.

I know that 1976s Bi-centenial Ikes were mixed, some 40%, some clad.
I think that's the only year that was done.
all other S-mint Ikes were 40%.
but not 100% sure on that.

Answer to your question below:


Quick Ike guide:

All P and D mints are Copper/Nickel clad.

All '71 and '72 S mints are 40% silver, issued in in Brown-Proof or Blue-uncirculated packaging. Proof sets were issued as 5-coin sets, Ikes were not included.

'73 and '74 S mint Ikes are produced in Clad and 40%. All 40% were issued in Brown-Proof or Blue-uncirculated packaging. S mint Ikes issued in proof 6-coin sets are Clad.

1976 S mint Ikes are produced in Clad and 40%. The 40% uncirculated Ike was issued as a 3-coin set in red packaging. The 40% proof Ike was issued as a 3-coin set in a blue slip cover. 3-coin sets included 40% quarter, half and dollar. S mint Ikes issued in proof 6-coin sets are Clad.

1977-S and 1978-S NO 40% Ikes were produced. S mint Ikes in proof 6-coin sets are clad.

Thanks Verbane, that is most helpful. Going to print that so I can keep it handy.

One correction to above, I have edited to reflect this. San Fransisco issued only Proof 5 or 6 coin sets, Uncirculated sets were produced by P and D only. The only uncirculated coins issued by San Fransisco were the specially packaged silver coins. The 71 to 74 Blue Ikes and the 76 Red Ike set.

So if one ike is sealed in the rectangular proof case and in the embossed brown box, then is it always 40%?

Yes sir it will always be 40% silver,........ that's unless someone cracked out the original and put a clad one back in, but that would only work for the 74-s and 73-s proof ones

What's the tissue test?

Somebody wanna help with this one....kinda braindead this morning.

Silver will look brighter under a piece of tissue. The clad will be alot darker. A significant difference. I'm just not sure if the 40%ers show up that well.

Yes.

They can be edge checked like halves.
Or weigh them. CuNi is 22.68 grams, Ag is 24.59 grams.
Or the ring test.

Like the half, the 40% coins are actually clad in construction. The outer layer is .800 fine. The core is .210 fine. Experienced eyes should easily be able to differentiate the CuNi from the Ag specimens.
