|Mirror brockage errors are caused when a coin that has already been minted gets stuck in the press and remains on the die. Then another coin blank is fed into the press where the die strikes down on the blank that hasnít been struck and instead of two dies pressing into that blank coin, one side of the blank is pressed on to the already struck coin which creates a mirror image of the first coin into the second coin. The error with the mirror image has that mirror image of the design incuse into the surface of the coin instead of being raised up like a normal strike. Mirror brockage errors are quite rare and are among the most sought after of all error coins. The coin offered here is a full obverse mirror brockage error of an undated Great Britain Victoria Sixpence which was struck between 1838-1863 which has been graded VF20 by NGC and is encapsulated in the newer-style edge-view holder. The incused mirrored side of the coin is facing forward in the holder with the regular obverse strike of the coin facing backwards in the holder. The piece a very even medium grey color which exhibits considerably more detail than the assigned numerical grade suggests. The coin has no significant hits, marks or spots and is a wonderful overall example of this scarce but popular error.
Because of the difficulty in capturing the overall look of the coin in a single image, I have also included a short high-definition video of the coin towards the bottom of this listing in an attempt to give you a better idea of what this coin will look like in hand. Please note that you may need to adjust the video quality to 1080p and may need to increase the size of the video to full screen in order to see the coin in maximum detail.
