Dropping coins is just asking for dings and dents.

Not like we're dropping coins worth anything past their FV.

And even with an audio-program, there's going to be that constant distrust!

I just simply stay-away from '67 quarters and dimes

Here's a thought. If the two types have the same weight, have the same diameter, but have different densities, they necessarily must have different thicknesses. The more dense coin would need to be thinner. Since all coins have "topography" (areas of high and low), it's unlikely you're going to find a single thickness published anywhere. Thickness measurement is further complicated by wear. But if there's a location on the coin where a "non-wearing" (protected) area on the obverse (the background or field) lines up with another non-wearing area on the reverse, and you measure every coin at that location, you should find the coins separate into two distinct groupings. The set of thinner coins should be the 80% alloy and the set of thicker coins should be the 50%.

Full destructive chemical analysis should yield trustworthy accurate results to determine if a coin is / was 50% or 80% silver.
To be honest, I am not keen on this approach.

Perhaps XRF testing (non destructive), would yield even more accurate results, but the fee for testing is not justified.
Drop ping test quite OK on melt value coins.

According to Krause, there is no difference in the value of the 1967 50% and 80% 10 Cents and 25 Cents coins, across the grades.
I cannot think why anyone would want to take a silver coin out of a 1967 mint set to test it for fineness, especially when it can be safely assumed that it is going to be 80% fine.
For these reasons, my attitude would be to just collect all of them in superior condition, without question.
