V5 is the card #. All MLP cards have a assigned letter & number. This happens to be puzzle piece v5, meaning it's piece #5 out of a 9 piece binder puzzle =) hope that helps!
Yes, thank you. I realized it after I commented. Listia is crazy and doesn't allow us to edit or delete comments,then my phone froze. You were great in response time and the explanation. Thank you very much.
