I play at Canterbury Park which has those same Bud Jones S2 chips. They just replaced the $1's & $10's. All other denomination are still in play after 24 yrs of heavy use in a very popular card room.
I would guess that something like 75% of all the chips in play were Original chips & of those, maybe 5% were/are cracked.
No reason to second guess your desire. These chips are very nice and will wear 1000% better than any compression molded chip. They are basically indestructible. I don't see how you would ever crack one in a home game unless someone was really trying hard. If you are buying new it isn't an issue at all and if you are buying used, just buy a few extra and sort out the cracked ones and sell/toss em.
Problem solved
