Gronkowski's graded rookie refractor bids triple the raw price

Rob Gronkowski's 2010 Topps Chrome #C112 rookie sells near $22.50 USD raw. An Orange Refractor of the same card in PSA 10 drew 20 bids on a live auction.

Sports Collectors Digest reported him becoming eBay's hobby ambassador on September 4. He is a regular on eBay Live with a pack-ripping series called Gronk Geeks Out.

At The National in Chicago he opened a 2010 Topps Chrome Football hobby box, pulled his own rookie and signed it on the spot.
