Wilcy Moore Single Signed Baseball 1927 Yankees JSA LOA/ PSA Hologram. Wilcy Moore was a key member of the 1927 New York Yankees World Championship team. As one of their top starting pitchers he boasted a 19-7 record with a 2.28 ERA! Moore died in 1963 and clearly did not sign a lot when he was alive. There are only three Wilcy Moore signed baseballs known to exist including the example in this listing. In 2005 Lelands Auctions sold a Wilcy Moore signed baseball for a $7,186.18. Over two decades later collectors are still fighting over the same couple of known examples.
