my question is this, how do these Brockage errors make it out of the mint, from my understanding, mint employees are checked my metal detector before they leave the mint, so how do these make it into existence?
From my understanding the coins are shipped out of the mint in large bags which it is easy for a brokage error to be in without being noticed. They are found by the company that does the rolling. Richard
A brockage error is the same size and shape as a regular coin. It will easily pass through the same equipment, counters, rollers, etc.
No it is a cointhat is struck between (Usually*) the anvil die and a coin stuck to the face of the hammer die. It results in a coin that has a raised image on one side and an incused image of the same design on the other side. * You can have a brockage created by being struck between a struck coin still in the coining chamber and the hammer die. In that case the brockage is also struck outside the collar and is also a broadstrike. So it would be called a broadstruck brockage and it would be larger in diameter than a normal coin. (A regular brockage is the same size as a normal coin.)
this is what i meant, heres a pic from another post (thanks "lostdutchman" for the pic he posted, this is what i meant by how was this released from the mint
