I rarely see comments on pricing on Vintage Weights & Physical Culture. These buns were on the site, not for sale, but a request for information. A member mentioned the 35s are valued between $250 and $350. I am not sure if the $4-$5/pound is typical or if the 35s are unique. They are cool and all, but I could not shell out that kind of scratch.
Listed for $325 and $300 respectively on Ebay. No bids so far.
