Bo Jackson signed Raiders mini helmet with Steiner numbered hologram. I'm not sure if it ever had a COA card. Because of the number on the COA, you can find it in their database. I included all of the information from the Steiner hologram database website. You can print out any of that proof that you want, but it won't be sent with the helmet.
