Feel that the important part, given the low attendance of STH for the palace game, will be bringing 'new' fans to a game. Hence the desire for £1 concession tickets. Give a chance for some new people to watch a home game, get hooked and become STH further down the line.
Would accept £25 for adults as top rate but if it is an afternoon KO on Sat or Sun (can't see us being a TV priority) then how about kids for £1? (max 3 per adult say)
