1994 20c Brockage? Please Say 'Yes' ...

Looks like a shed job to me. But warrants closer inspection. Struck through with a hammer is my guess.

Sorry, but we can't say "yes". It's not a brockage. A brockage looks like a perfectly normal coin on one side, and the other side completely blank except for a mirror-and-incuse version of the exact same design on the perfectly normal side. If your coin were a brockage, the queen's portrait should not be there at all. Here are some good brockages.

Nor is it some kind of die clash. The dies do not have a high rim like that which could create a clash. When dies smash together with no coin blank between them, the parts of the die that hit each other are the highest points on the die - which become the lowest parts of the coin. A die-clashed coin should show no damage on the coin's high points (the obverse legend should all be clear and readable, not mashed-up like on your coin), but an amount of new detail raised up in the fields and other low points. Here's a typical die clash.

Sadly, your coin is PMD - a "vise job" - two perfectly normal coins have been squeezed together, either deliberately (like in a vice) or accidentally (like if two coins were used to keep a heavy piece of furniture level).
