United States vs Europe
Same card, reverse holo print, two marketplaces.
Europe is 19% cheaper than the US for this print. Before acting on that, count shipping across the Atlantic, customs on the way in, and the risk of a card travelling in an envelope.
Converted at the European Central Bank reference rate for 2026-09-23. Currency moves on its own — the gap shown here is the gap on that date.
Last 30 days
Cardmarket rolling averages for the reverse holo print.
| Window | Average sale |
|---|---|
| Last 24 hours | €0.35 |
| Last 7 days | €0.31 |
| Last 30 days | €0.42 |
The 24-hour average has fallen 17% against the 30-day average — €0.42 to €0.35. A single day is a thin sample; treat it as direction, not as a price.
Note the weekly average of €0.31 sitting outside both the daily and the monthly figure. That happens when only a handful of copies change hands, and one sale drags the average with it. On a card this thinly traded, none of these three numbers is a price you can count on.
About this card’s market
Asking prices run from $0.15 to $19.92. A spread that wide says more about individual listings than about the card — the market price above is what copies actually sold for.
In Europe the card has been sliding: the 24-hour average is 17% below the 30-day one.
It sits joint 89th of 111 priced cards in Steam Siege, in the cheaper half of the set.
