I think you can get about $200 for them. If you sell them separately may be you can get a little bit more. the club labeled P is your Pitching Wedge which came with 3-9 as standard iron set. you didn't mention what kind of shaft(steel of graphite), and flex, steel shaft would be a little cheaper.
Here is a break down price when they were new:
Titleist 3-P:$300-400
Callaway driver:$150-200
Ping Putter: $110-130
Bag:$50-125
email me if you want to sell that Callaway separately.
