Alonso rookie cards hold flat as he reaches 300 home runs
Mets fans gave the visiting Oriole a curtain call; his rookies trade in the teens.
By Jeff Newman
Pete Alonso's 2019 Topps #475 rookie in PSA 10 has a $16.55 USD median across 25 auction sales in the month before Tuesday's game. Alonso hit his 300th home run at Citi Field, a ninth-inning solo shot off Kodai Senga to tie it.
The 2019 Topps Chrome #204 in PSA 10 sits at $24.99 USD across 13 sales. Neither moved on the milestone.
Mets fans chanted until he came out of the Orioles dugout for a curtain call. We posted Yordan Alvarez's rookies holding flat two days earlier, in the RBI race Alonso leads.
