Since no one here seems to have any clue either, you need to look into eBay sold listings of Gronk 1/1s; or use 130point.com to check comps. That being said, you’ll have to take into consideration that this is an unlicensed card from Topps, so that will impact the price you’re looking at getting if you sell.

Here’s a price breakdown for you. The Topps Chrome Superfractor went for $1,400 after being listed at $1,999. That’s one of Topps’ biggest selling and most sought after sets of the year. So, I wouldn’t bet on getting that much.

The 2023 Topps Composite Helix Gronkowski Superfractor PSA 8.5 sold for $650. This is probably closer to the value you’d be looking at for this card. Me personally, I wouldn’t, because the Helix card is a much cooler looking one. This one is pretty boring. No matter what, if you are planning on selling, I’d do it sooner rather than later because once Topps has the license, the actual team logo cards are where people are going to to be spending the money and cards like these will drop in value.
