Hi Dennis, the official list from TnP is the authorative reference source. It has 174 cards in total.
The first checklist I posted on the thread (as attached) related to work that Sergb and I had worked to determine what cards actually existed based on pack openings before the TnP checklist was officially released.
So the main differences are as follows:
The TnP checklist references Liam Rose, who is actually a CCMariners players, but it is immediately below Joshua Rose on that list. We have not found a Liam Rose cards, but we have found a Liam Reddy card. So we assume this is a typo on the checklist, and this was questioned by R2GFifa on the TnP Twitter account, but no reply was provided from memory.
The checklist that I have posted includes 2 cards that are not on the TnP checklist - Matthew Leckie (socceroos) who has a confirmed card, and Tom Doyle (WP). The Doyle card was confirmed by Sergb, but has become somewhat of a mystery as it has vanished. Sergb is dealing with a personal issue at present, so his focus is elsewhere at present, but at some point in the near future this can be explored a bit further. However, to date his card do not appear to have been found in other packs.
At present there are 9 cards on thr TnP checklist that nobody has found in any pack openings - the 7 Melb city cards, Ivan Franjic (Bris) and Bailey Wright (Socceroos).
So the checklist posted based on work progressed by Sergb and myself is by far the prettiest

but it may simply add to the confusion associated with this series. Hope this explanation is of some help, but if you have specific questions let me know and hopefully I can answer them.
