Weird high offer on a low $ bin name on Uniregistry ?

I just got an offer for a name that had a low to mid $xxx bin price.

Potential buyer just offered $9k on a name but my bin was less than a tenth of that. I'm concerned that either its a scam or the buyer screwed up. Its not a normal number like $9000 or $9500, rather its $9021, which seems odd.

Not sure what best to do next. If I accept and it turns out the buyer typed it in wrong I could scare away buyer, but it could also be a scam or bot.

What to do ?
