I have a few Negro League patches available for sale.  All are in perfect condition, and were found in a mixed box of patches dating to the 1970s and 1980s.  Not sure when these would have been made, but my guess would be around that time period.  I do not believe these to be iron-on.  They are actually very nice quality and fairly thick... definitely patches to sew. 
Overall size is 4"x4", and all embroidered.  
$7.50ea including shipping in the US.
