Fort Sheridan Medal With Die Clash Errors

This isn't a die clash, but a coin hammered (squished) between two other coins. Notice how the 'clashed' elements go over other design elements. If it were a real die clash, the secondary design would not overlap the original design and push the previous design down. It is an interesting medal though; I have not seen this one before.

By golly, you're right! It is a 'squish' job! I jumped to conclusions!

And, not to forget, a die clash would be a raised element on a coin. These appear incuse.

Here I disagree. A die clash would be an incuse element on a coin.
Design elements on coins, say, the legend, are normally raised. So, on the original Die, those elements are incuse.
When that original Die strikes the opposing Die (clashes with it), a raised element is left on that 2nd Die.
The 2nd Die then hits an incoming planchet, creating an incuse element.
