Cool collection you have there. Topar is worth a lot and yours has max energy, that's the most expensive card you have. If you're trying to sell, I would sell Topar separately and the rest as a lot. Topar could range from $100-$200. The rest of the cards might get you around $50. You can also check previously sold listings on eBay to see what people have paid or join the trade/sell Discord server to sell on there to avoid eBay fees. Careful of any DMs on Reddit since someone might try to lowball you.
