The AMF Exacta Pro Roll bowling ball, especially if it's in good condition, can have some collectible value, particularly among bowling enthusiasts or vintage sports equipment collectors. The value can vary based on factors like condition, demand, and any unique features.
If you're considering selling it, check online marketplaces like eBay for similar items to gauge pricing. If you find it's not worth much, donating it to Goodwill could be a great option, as it might help someone who enjoys bowling but can't afford new equipment. Ultimately, it depends on your preference for either selling or donating!
