Rare Stamp Acquisition Program?

Has anyone ever heard of this group?
Is what they sold legit?

I remember this type of "investment" stamp offerings in the 1980's or so, when investment operators were hawking these. From my recollection, the stamps were most often correctly identified for catalog listing, but the condition was almost always less than desirable (centering, condition, faults).

If there is a cited certificate (PF, etc.), it would be worth checking validity, however back in that time period, faults were often not completely disclosed.

The following example is from ebay, Lot 302693965138



And reverse...



No information provided as to who the certifying authority might be.

Dated 1986. Interesting that there is no company name.

Perhaps mml1942, Bob, back by the radiator, was the in house expertiser and office supplies clerk.

The style of the "certificate of authenticity" looks very familiar, perhaps from one of the FDC-producing companies.

Or perhaps Greg Manning or Marlen Stamps.
