1800 Draped Bust Silver Dollar. BB-195, B-15. Rarity-4. EF-40 (PCGS).The obverse and reverse are toned in a uniform dove-gray patina with slightly darker gray on the high points of the design. Rather impressive in terms of strike as Libertys hair curls and the stars are all full, with complete device definition found on the reverse as well. Examination finds hints of luster in the recesses of the design as well as a couple of minor toning spots located on the reverse. Notice the die rust on the upper reverse in the form of raised tiny lumps, this effect was caused during the humid months in Philadelphia where this die was not properly stored with enough grease to repel the relentless humidity, which formed rust over time. When the reverse die was used for coinage, the rust pits in the die cause raised lumps on the coins struck, a feature sometimes seen on our coinage from this era.
