What's New in CenterMint
2.1.0
October 27, 2026
What's new in 2.1 ■ English card catalog Switch the catalog between Japanese and English cards at the top. English sets, card numbers and prices have their own pages. ■ More Japanese market detail See how many sold in the last 30 days, the price range at card shops, and shop prices in other regions. ■ Target price alerts Set a price and get notified when a card drops below or rises above it. 1 card free, unlimited with Pro. ■ My collection Add the cards you own with quantity and what you paid. See the total value and your gain or loss at a glance. Pro adds a value-over-time chart. ■ Prices in your currency Under the main price you also see about how much it is in your own currency. ■ Prices by region On a card page, switch between Japan, the US and Europe. When a region has no sales yet, we tell you why. ■ More US prices When a card has no recent US sales, you now see the lowest price on sale instead of nothing. ■ Clearer price notes When sales are few or prices vary a lot, a short note tells you how to read the price. ■ Search by card number 025/165, 25, #25, 89/88 and promo numbers like SV-P 001 all work now. ■ More accurate Japanese prices Look-alike printings, first editions and accessory listings are no longer mixed into a card's price.
