How much could I sell my Lake Balls for?

I buy lake balls, main name ones eg Bridgestone, Nike, Callaway, Taylormade, Srixon. I buy Pearl / A grade mix. I pay around 30p each in the off season, it goes up to 50p a ball in the season. I'm tight and look around for a bargain. For that I expect them to be in good condition, as Pearl/A should be. Not perfect but very good. Any decline and they start being A- / B grade and then you are in 10p-15p territory.

Ebay is the home to lake balls so have a look on there for a guide. Best bet is to group brands together, eg 20 x Taylormade, 50 x Callaway.
