There appear to be 10 in this set. I bought the other eight a while ago and posted about them HERE.
I haven't checked the mailbox yet today. It's below 0 and I only want to make one trip so I'll wait until I'm sure the mail has been delivered.
Updates on my Sports Memorabilia collecting hobby, including through the mail autograph successes and in person autograph signings. Feel free to email me with questions: email@example.com.
