I thought the market would be so dry by now you will literally find nothing worth buying on both FK and HF. My two friends who I bought tags for still have theirs and get offers over $500. If you can find a trustful seller, go for gold.
3 char's are randomly priced these days.. new kids get them and sell them for 30-90$. It's ridiculous how everyone thinks that they are worth some arbitrary amount, not even basing it off the market.
