Classic Collectibles LLC Scam trying to sell people "misprint stamps" Nationwide

Some guy Randy called me today saying we had talked 4 months ago and he had sent me some information.....none of which I remembered. Regardless, said we had spoke and at the time he didn't have an investment deal small enough for what I was looking for but just today one came across his desk. Starts telling me about misprint stamps that collectors go crazy for...yadda yadda yadda. He has something that just came out and it is 1920 1 cent George Washington Stamps that are missing the perforated edges. He has five sets total (two per set) and has already found buyers for 3 of them. Oh yeah and there are only 25 sets in the entrie world. I tell him I am not interested but he keeps going, then says he is prepared to fedex them to me with the certificates of authenticity....All I have to do is give him my credit card number and they only charge me if I don't send them back. $1,900 for each set and they appreciate in value 18% to 23% annually for the first three years and 9% to 12% (or something like it) for every year after. Gave me an expample of one his "long term clients" that bought a stamp for $750 then sold it 3 years later for $6,000. WOW...why isn't everyone in the stamp game??/ I told him no again and he then hung up on me.....Bad company, Bad People, and come to find out they used to be called Continental Collectibles. After researching these guys I found a few complaints same as the above, same pitch, same phone number just a slightly different name.
