I've got a bag of more than 50 Titleist Pro V1 and V1x golf balls available for $20. I've graded them "C" because they might have a scuff mark or someone's ball mark on them, or slightly faded paint. I usually play these as "water balls" because I wouldn't mind losing them. These were mostly found at Bay Palms so some them might be yours!
I've got another bag of 50+ Titleist Pro V1 and V1x golf balls that I've graded "B+" simply because they don't have the shiny paint of a new ball. These don't have any scuff marks but they might have a minor "mark" someone's put on it. You can have these for $30. Online at "Lost Balls" a bucket of 48 "Good" used balls goes for $60 so I would consider these "B+" balls as half priced.
Let me know if you'd like to see them and I'll bring them in.
