The card on the left is known as the "Mystery Card", I believe there around 40 known to exist. The one on the right has a factory Sawcut and a super cool looking print offset.
Mystery Card $50 Shipped
Sawcut with Print Offset $150 Shipped
Both for $180 Shipped
I would also trade for lower grade to complete beater T206s or T210s.
You can find a lot of great info on this site dedicated to this amazing card.
