PCGS 2000-P Sacagawea Dollar quadruple struck with the 1st strike normal, then struck 3 times 75-80% off-center. A dramatic multi-strike, with the many strikes being visually eye-catching.
There are a small number of these out there, but they are very popular and only occasionally come on the market for sale. Scarce as a whole, but somewhat available with some searching.
MS65 with light toning. The dark areas on the reverse are either planchet stains (pre strike stains) or are grease or a similar substance struck into the coin.
