Vise job/Squeeze job - These terms are used in reference to coins with an incuse design impressed into the surface. Such alterations are designed to mimic a brockage,double strike or clash.
Usually these coins are made by pressing or squeezing 2 or more coins together in a vise,smashing 2 coins together with a hammer...along with many other methods to produce the same effect. These are simply post mint damage and are NOT genuine mint errors.
If you have an example that you have come across or have questions about,feel free to post them here
Here are a couple I have came across personally in circulation.




Here is a genuine example "Double struck in collar". Note the design elements are raised and not incuse. These are quite scarce and hold a nice premium.
