Ever Heard of the Green Boy Packers?

The Green Bay Packers recently offered stock in its franchise for just the fifth time in team history. A guy named Arvind of Winnipeg went all out and bought one share. Here's what his one share looked like when he received it.

Apparently the word "Boy" is in place of "Bay" everywhere on the certificate.

I wonder if this makes the certificate rare and valuable? I'd take it to the gang at Pawn Stars if I were this dude!
