I stand by 'out of blue' comment. For argument's sake, let's assume that these were struck around the 1990s as it's impossible to prove when. These are not heard of or mentioned in any catalog as far as I am aware. For these to appear about 30 years later - makes me wonder if someone is selling for their retirement funds. Timeline matches for someone that worked during that era and just retired. A single source makes it even more strange - did the person know someone in the mint? Or the person worked in the mint... Someone knows.
Common error coins would be off center, broadstrike, brockage, double strike etc. What I am more interested are error coins that are more likely to be intentional such as wrong planchets, mules, overstrikes. Typical examples would be 2000 10 cents / dollar mule, 5 cents struck on 1 cent planchet or the more famous 1981 20 cents struck on Hong Kong $2 planchet.
Wrong planchets and mules are 'doable' using available tools in the mint. Overstrikes on foreign coins (or objects like button battery!) on the other hand is clearly intentional (if genuine). This requires a mint staff to walk in with random (or selected?) foreign objects, manually place them to be overstruck AND walk away with them. There is no valid reason for trial strikes as these are not first year type. How many more strange overstrike examples are out there? The mystery continues...
