Where the market is now

Griffin’s 1st Bowman Chrome autograph now sells for about $489 raw and $1,187 in a PSA 10, based on recent sales tracked by SportsCardsPro. Live eBay listings for the raw card ask around $800, and asking prices usually sit well above what cards actually sell for.

His 2026 Topps Chrome rookie autograph arrived in late July. Raw copies sell for about $249, roughly half the price of the 1st Bowman, and PSA 10s are close to the 1st Bowman’s PSA 10 price.

In April, before any of this, the raw 1st Bowman auto had an asking average of $1,154 across 198 listings. Those were asking prices during debut week, so they don’t compare directly with today’s sold prices, but the direction is clear: the debut premium has come out of the market as he settled in with a .728 OPS over 80 games.

Which card is which

1st Bowman Chrome auto (2024)

His first Bowman Chrome autograph, from 2024 Bowman Draft. The hobby’s anchor card for a prospect and the one most collectors mean by “his auto”.

2026 Topps Chrome rookie auto

His official rookie-card autograph, released in July 2026 after his debut. Cheaper than the 1st Bowman for now, and the one new collectors often find first.

The April debut snapshot

This section is the original article from April 3, 2026, kept for the record. Prices in it are asking prices from that week.

Griffin made his MLB debut on April 2, 2026 with the Pittsburgh Pirates, the first teenage position player to debut since Juan Soto in 2018. He had played five games at Triple-A (7-for-16) before the call-up, and he signed a 9-year, $140 million extension before his first big-league game, the largest deal ever given to a player before his debut.

Before you buy

Sold beats asking

Listings ask well above recent sales for most cards. Use the sold price as your guide.

Grading changes everything

A PSA 10 sells for more than double the raw card. Check condition carefully on raw copies.

Debut premiums fade

Prices peaked in debut week and came down as the season settled. Big news moves these cards fast in both directions.
