Looks normal to me. Definitely not 90% silver.

40% nothing special here.

There were no 90% silver planchets on-hand in 1970. 40% silver halves often show no copper on the rims.

You have answered your own question when you show the package is a mint set, not a proof set. Mint sets will show copper on rim. The proof set silver will show silver on the rim also, there were no silver Kennedy halfs produced in 1970. Silver sets will have the S Mint Mark and the package will say silver. Bottom line is your coin is a normal unc. 1970 D.

So, yes, it is possible that your half is 40% silver - but it is normal for these sets.

Quote: My question is, If you look at the edge of a 40% Silver coin, will you see the copper layer? Sometimes, yes, because it is a silver clad coin. The cladding is 80% Silver 20% Copper, while the core is 79% Copper 21% Silver. The core having more copper will be darker than the cladding, but not as easy to see as 100% copper on Cu-Ni clad. Just because you cannot see it does not mean it is not there.

As others have stated, your coin is 99.9999% likely to be a typical 40% silver 1970-D Kennedy half dollar. My advice is to not cut it out of the Mint packaging. A brilliant uncirculated 1970-D Kennedy half can be more valuable than other 40% silver half dollars. As mentioned in the article that Dearborn linked, it was the last circulation 40% silver Kennedy released by the Mint, and the way they did it was unusual. Therefore, the intact packaging might add to the value. Many times the 80/20 silver-copper clad layers are indistinguishable from the 21/79 silver-copper core. If a 40% coin undergoes significant toning, you might be able to see the core edge as a faint color difference. It might also be more visible under certain wavelengths of light that are reflected differently by copper vs. silver, or with different physical camera filters.
