Looking for someone who knows the value of the Overseer Radio. If anyone knows the value of this item, it would really help me out!

Hi, everyone. Could someone tell me how much this effect called “Snowflakes 2017” is worth? It looks like an effect from an old event in 2017, but I'm not sure if it's worth anything. On Supreme, it says it has a rarity of 7, but I don't know what that means. Is it a common effect? Rare? Super rare? If anyone can help me, I'd really appreciate it!!!
