In a follow-up email, Richard also gave me some notes on the cards he sent me. He pointed out that two of the cards he had included were variations that perhaps weren't obvious. He was right, because I had totally missed them when I looked through the cards!
The cards in question were the #1 card in the Pinnacle set from 1998. They look like this.
I already had this card in the Pinnacle folder, so put it to one side in the little pile of cards that I knew were duplicates. (There was some crossover between Richard selecting cards to send me and the parcel with over 100 cards in arriving from France, so there was a small overlap in contents.)
If I had thought about it, though, I would have realised that I blogged this card along with Tony's other Pinnacle base cards back in July last year. Richard had checked my list on Trading Card Database, so he would have known I had this card already. I should have realised he would have sent me these for a reason. (Lesson - never doubt a supercollector!)
The differences are in the cardbacks!
Card Number 749: Pinnacle, 1998 (Home Stats parallel); #1
