Coastcapital Financial Services sent me a letter telling me I won $355,000 and containing a check for $4,650 to cover processing fees Los Angeles California

Today I received a letter telling me I won $355,00, the second prize in a sweepstake. The letter also contained a check for $4,650, purportedly to help cover the "processing fee," shown as $3,850.

I was advised to contact the claim agent, "Allen Nelson @ 1778-385-0574" to activate the check.  I was also advised to not act on "this notice" until I contacted the claim agent.

 The letter was signed "Sarah martins" (sic).

The letter sounded suspicious to me and to a friend of mine, so I did a search for "Coastcapital Financial Services," and discovered several "scam" reports against the company.
