The 1994 Nelson Mandela Error Coin is a rare and unique piece from South Africa, featuring a nickel composition and a proof strike type. Graded as PR 68 by PCGS, this uncirculated coin is a valuable collector’s item due to its error variety. The 2000 Smiley Extremely Rare coin adds to the allure of this set, making it a sought-after addition to any coin collection. Both and I will add 50 more coins my personal collection.
