Here's another you may be interested in. It is a 1918 Spalding Colored League Trophy Cup made by Dieges & Clust. This pre-dates the Negro National League by 2 years, and was likely awarded to a "Barnstorming" Team Player.

It realized just under $1,000 back in 2002. An interesting piece, to be sure. Hope this information is helpful.
