Factory Additions or Sunday B. Morning
The stamp on the back decides the order of magnitude. Factory Additions sheets from the 1960s sell in the tens of thousands and up; Sunday B. Morning editions of the same images typically under $2,000.
Two markets under one name: Factory Additions screenprints in the tens of thousands, Sunday B. Morning usually under $2,000.

What a Warhol print is worth depends first on who published it. Screenprints issued by Warhol's own Factory Additions in the 1960s sell for tens of thousands of dollars and more — single Campbell's Soup I sheets have sold for about £24,000–35,000, and complete 1967 Marilyn portfolios for over $1.5 million. Later editions stamped Sunday B. Morning on the back are not counted among Warhol's own prints and typically sell for under $2,000.

Warhol's prints are among the most traded works of the post-war market, and one catalogue sorts them: the Feldman and Schellmann catalogue raisonné, which records each image's edition, publisher, printer and markings. A screenprint with an F.&S. number that matches its entry is the market's reference point.
The confusion comes from Sunday B. Morning, the name stamped on the back of screenprints of Marilyn, Flowers, Campbell's Soup and other images that circulate widely. They reproduce the same images, often in similar colours, and they are not Warhol's own editions; the market prices them as decorative prints.
Since the Andy Warhol Art Authentication Board dissolved in 2012 no body issues opinions, so provenance does the work a certificate would elsewhere.

The things a buyer prices in, in roughly the order they look for them.
The stamp on the back decides the order of magnitude. Factory Additions sheets from the 1960s sell in the tens of thousands and up; Sunday B. Morning editions of the same images typically under $2,000.
The Feldman and Schellmann entry records the edition, paper, printer and markings. A sheet that matches it in every respect has the strongest case the market allows.
Within a portfolio, some images and colourways are chased more than others — the most recognisable Marilyn and soup-can variants sell above their siblings.
With no authentication board, a paper trail back to the original publisher or a major sale does the job a certificate would. A thin trail is discounted.
Factory Additions prints with good provenance sell through the prints and post-war departments of the major auction houses and through specialist print brokers, where competition is international.
Sunday B. Morning editions and posters rarely justify major-house fees; a print dealer or online auction suits them better. Photograph the back, including every stamp, before asking for an estimate.
Indicative ranges for honest condition, never an appraisal or a quotation. The house buys, sells and values nothing; a specialist who can see the piece is the only one who can price it.
