The Pro-V is a custom logo. The VG3 ball is nominally a Japanese product. So it would be uncommon in the US. Calling it rare might be a stretch.

VG3 being a common ball in the Asian market and the other just being someone’s after-market logo addition makes these really only valuable to the individual that has them. No collector market for these.

I found a VG3 a couple weeks ago at my local course. I beleive they are for the Japanese market. But i have seen them on Ebay and Amazon. Not sure about the M&m ball.

The Titleist VG3 Golf Ball is a premium distance model exclusive for the Japanese market, featuring a super lower spin fleximer cover and soft center multi-component construction. The new Titleist VG3 delivers low spin off the driver and irons for long, straight and consistent distance on all shots. The construction features a soft center for lower spin and an advanced 332 catenary dimple design with a Staggered Wave Parting Line A.I.M (Alignment Integrated Marking), which offers more consistency and length.

The M&M ball is most likely a promotional custom logo ball for M&Ms.

Rare? They pop up in golf shops along the coast where there are alot of courses. i.e., Myrtle Beach golf outlet stores.

Cut open the M&M ball to see if it’s got a peanut center, or just chocolate.
