How did you get the top 3 highest sales ? Where did you look it up. I have a feeling that something should be between prince Julian and Alpha GF Frost Giant.
I'm probably wrong about this, but I feel like GF Archmage Arius got Sold (or traded) in the past, Maybe it was just for under 10k.

Also I know it would have been a more boring post, but 2 Regions have sold on Wax.
2nd was sold 4/12/2021 for 820k wax (460k$)

But it's a very cool post and it makes me really happy to see how some people have decided to spend such amounts on one transaction in Splinterlands.

Keep it up!
