I will check that. According to PeakMonsters, the current total value of my Splinterlands card collection is $672.33 USD. Maybe leasing out some of the better cards would give a few cents per day. That would be still better than the Legendary/Alchemy potion charges.

I give you some !PIZZA and some !LUV.

Have a nice day and have a nice weekend.
All the best. Greetings and much love from Hungary.
