Asking for advice, please.

Iím having a clear out of all things football. I have a signed shirt & signed ball and I was going to put them on eBay/gumtree. Iíve met a young lad who visits his Gran in the nursing home my wife is in. Talking about Saints, I mentioned the shirt & ball and he was very keen to have them. I told him I would include a big bundle of Saints progs and other written material.

The question, how much should I ask for the items? The money is going to go to Ward G7 at the General Hospital.
