Niewmismatic Error Coins

Malaysia 1969 Security Edge 50 Cents With Reverse Struck Through Mint Error NGC MS65.
Rarity:RRR
Among the NGC encapsulated items that I collected yesterday when I was in Singapore, is a piece of Malaysia 1969 50 Cents with security edge (SE). It was graded by NGC as Reverse Struck Thru Mint Error in MS65. This Mint Error coin is belonged to my customer from Sibu, John Ting Sie Wei.
Struck-through errors occur when foreign objects fall between die. A "struck through" coin happen when an object is set to rest on a planchet before striking. When the dies strike the coin, the object's impression is pressed into the surface of the coin, producing a glaring mark on the surface of the coin. Common examples include staples and cloth. Another good example of a struck through impression is when die grease fills the crevices of the die, so when the coin is struck, it causes a weak strike, and gives a smudged appearance.
The most collectible struck-through errors are those with the foreign object still embedded in the surface of the coin.
