I have been playing Splinterlands for over a year now and this is the first time getting a legendary gold foil from Rewards. The reward is from Focus Chest Reward in Silver League Modern Format. The card I got is Harklaw from Death Element and has current value of 29.950 USD. I sold the card to Splinterlands Marketplace in order for me to buy more cards that I can use in improving my deck.
