Bugger all I reckon, they'd be a dime a dozen, only a real collector would consider buying it, if it was a signed premiership jumper, now that would be different, I realise it's their first season but not having a great deal of supporters your target is limited, put it on ebay and auction it, I doubt you'd get more than $200-$250, maybe in 20 years down the track or when they win a flag it might become more valuable.
At the moment not that much but if you keep it for your great great grand kids it could be worth a lot I have port powers very 1st home ball not worth much at the moment but ill just hand it down through my family
I bought one at a Suns luncheon last year, cost me 450 unframed, I was 3/4 cut and didn't know what I was doing, the Mrs still doesn't know about it, with Gazza and Special K's signature it might be worth something one day but I reckon I paid overs...again
