George V 5 Cents 1921 AU Details (Environmental Damage) PCGS, KM22a. The last year of the silver 5 Cents series, and by far the rarest date. Most of the mintage was later melted. The example pictured here suffers not from environmental damage, but from an old cleaning. In any event, this specimen is far better than most seen on the market today.
Estimate: 6000-8000 USD
