10 ) Make money by OVERPRINTING stamps.!!
My personal opinion is both are forgery!!
Don't you think it's easy to make OVERPRINT stamps and make money.
If you sell regular stamp without any OVERPRINT such as SPECIMEN or SERVICE or STATE NAME then it will have no buyer or you have to sell it at 1/10 or 1/20 price of OVERPRINT stamp.
Just buy stamp and use your printer to OVERPRINT SPECIMEN on it and SPECIMEN stamp is ready. Do It Yourself (DIY).
There are no buyer of following Montserrat stamp of famous people for $5, so buy it and overprint with SPECIMEN and you can make $70 or $150.!!
My opinion is same way like other Expertising person or committee or society take responsibility of their opinion.!!
So if you buy it even with Expertising certificate, you are not sure whether it's GENUINE. !! and you can loose your money because no liability.!!
