offers Offer on GoDaddy, is it fake?

I bought a domain 10 years ago d/e/d/i/s/e/r/v/e/r/dot/com which I put on GoDaddy auctions and forgot about it.

I received multiple offers last night through GoDaddy one for $7,777 and another for $10,000 within minutes. My gut tells me this is too good to be true and not real. However, I then think does somebody know something I don't?

I have not had any involvement in buying/selling domains for years so wanted to get some advice on what to do. Do I just accept and see what happens?

Thanks in advance.
