Great Britain. Shilling, 1817 R/E. S.3790; ESC-1232A (R3); KM-666. George III. GEOE: over GEOR: on obverse. A superb mint state example of this popular error coin, and probably the nicest specimen on offer in many years. The error (an E punched over the R in the abbreviated version of the king's name) is bold and clear, and the whole coin shimmers with original mint luster. Very desirable. Extremely rare. NGC graded MS-63. Estimate Value $1,000 - 1,200
