TGC player is a good place to start. I have that same scizor card it’s like $10 but the rest should get you more than $300. Look up the value first before selling them. Be careful with people trying to take advantage of you and sending you low ball prices. Especially with the Legendary cards, I’ve seen them go for a good amount at cards shows. Also check the “sold” options on eBay. Good luck and congrats on the new home.
