Coloured AFL/NRL Coins From Ballot

[planchetflaw]

Had a run through on eBay yesterday but could only find the regular cards. When it says Signature Cards are these cards with a blank space to be signed by the player (by the person buying the card)? Or are they actually pre-signed? Or a buzz word for a premium effect on the card like foil?

Signature Cards I really can't comment because I haven't bought either of these sets
