Japanese Venusaur Gameboy Promo

What is the value of a Japanese Venusaur GameBoy Promo? I accidentally won one (I didn’t even realize I won it until a few days after the item ended :laughing:), so I have to pay for it. I don’t want to keep the card, so I want to know how much I can sell it for. Also, it’s listed as Mint, so I was wondering if it would be worth it to get it graded.

Here’s the listing: Pokemon rare card japanese game boy venasuar promo, in mint condition

Thanks to anyone who can help :blush:

Id say less than $20

So it would not be worth it to get graded. Poop ):
