Great gloves and great advice Joe & Mark. If there is any chance those gloves are tied to Baker, then whatever you do, DO NOT CLEAN THEM! King Patents in general are fairly common but are highly desirable. Yours dates to 1913 & subsequent as 1912 & prior were full webs, not 1 Inch webs, but if you can photo match them like Mark advised then they would be worth a ton of money. I would look for something 1919 & prior as he didn't have 77 home runs until the 1919 season I believe. I'm pulling for you man. Good luck!
Here are some catalog pics from 1913 for fun. Hope this helps a bit.
