Extremely Rare Bonded 10 pile-up Error 5 Afghanis 1961 Muhammad Zahir Shah

This eye-catching error coin was created when a press feeder system malfunctioned. The machine inserted a second blank planchet into the striking chamber instead of ejecting the previous properly struck coin. When this happens, the press will continue to strike, either until the coins are fused or until a Mint worker manually removes the offending coins. Due to the sheer volume of pieces produced.

Bonded coins are fused by the pressure of the strike. Any combination of coins and planchets can be involved. A stack of fused coins is called a “bonded pile-up”.
