The 311A was not designed to be stamped two times in the spot. if most of the other stamping looks the same it was probably an accident that happened during the manufacturing of a specific batch of guns.
The standard terms are "minting" or "striking". Sometimes you'll hear people talk about "stamping" or "printing" coins but that's really not correct. By convention, "stamping" a metal object usually refers to something other than a coin; e.g. a spoon or car fender, even though the production processes are related. And "printing" is incorrect, because coins clearly aren't made using paper and ink!
More information is needed - a description of the suspected error, the coin's condition and its mint mark (if visible). Also, to explain terminology, coins are said to be struck or minted. The term "stamping" is used to describe the production of things like spoons and car fenders. Not sure why there's a distinction, there just is ;=)
Im not sure, but i have a ring stamped with an ARJ as well. It is a silver ring and i believe there is also a stamping of a face as well.
It means nothing at all - if it is stamped Sterling that means it is 92.5 percent silver - if it has no writing or stamping on it - it may or may not be silver - it means you should have it tested by a professional so you don't accidentally blind yourself with acid
it is Stamping ink :)

In the heavy stamping manufacturing industry, there are not a lot of differences between computers used there and anywhere else. The most common problem I have come across while maintaining these computers is grime. In the two metal stamping facilities where I work the grime is made up of mostly oil and dust. The 50+ heavy stamping presses all use oil as a lubricant in the stamping process.
To stamp is stempeln (like stamping a time clock) or frankieren (like stamping a letter) or stampfen (like stamping your feet) or even stanzen (like stamping metal parts) in German.
