It was a rough estimation. I calculated it more precisely now and it looks like below:
Cards | Value |
---|---|
103 Commons | 103 * 0.017 = 1.751 |
39 Rares | 39 * 0.063 = 2.457 |
3 Epic | 3 * 0.310 = 0.93 |
1 Legendary | 1 * 1.96 = 1.96 |
5 Gold Commons | 5 * 0.80 = 4.0 |
1.751 + 2.457 + 0.93 + 1.96 + 4.0 = $11.098
So let's say it's $12 because some cards are worth a bit more.
I'm unlucky. I need to pay j6969 for opening my cards haha :D
