Cardmarket rolling averages for the reverse holo print.
| Window | Average sale |
|---|---|
| Last 24 hours | €1.80 |

| Last 30 days | €2.75 |
The 24-hour average has fallen 35% against the 30-day average — €2.75 to €1.80. A single day is a thin sample; treat it as direction, not as a price.
Note the weekly average of €3.41 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.
