NGC Cert # 6828485-001 CH XF 5/5 Strike 2/5 Surface "Edge chip"

A very well engraved, struck, and preserved silver coin about 2,500 years old. The incuse bird is almost untouched deep in its recess.
This coin is a very appealing classic art piece with an impeccable pedigree back to the earliest months of the Great Depression.
Based on the handwritten notes in the margin of 1929 catalog, attached, it looks like this lot # 698 sold for one pound and 16 shillings.
Who bought it? The director of the British School at Athens, Arthur M. Woodward.

(Silver, 22 mm, 7.86 g, 9 h). ϘΡΟ Tripod with three ring handles and legs ending in lion's paws. Rev. Incuse eagle flying right; rayed border. Attianese 11. Gorini 26-27 var. (orientation of ethnic). HN Italy 2108. SNG ANS 287. This coin can be acquired by museums because it is confirmed as having already been outside the modern boundaries of the country it was struck in (Italy) long before 2011 and long before the 1970 "Convention on the Means of Prohibiting and Preventing the Illicit Import, Export and Transfer of Ownership of Cultural Property."

You can read about the former owners of this coin before. It looks like it was Edmund Nordheim's until 1929 when it sold at auction to Arthur M. Woodward. It was sold from the collection of Woodward in 1962, and then we see it appear again in 2000 at Leu and Elsen before appearing here.
