Coburg porcelain factory. Google or search eBay and you'll see similar items.
Neither
Ferdinand Kaule,
E. Speiser,
Kuhnle & Hoffmann, nor
Albert Riemann used such a mark. Sadly this hollow "Coburg" ID template for such a mark is just as irremovable from people's brains as the constantly incorrect "Schaefer & Vater" ID for certain unmarked figures, or other nonsense like "Coburg-Dresden", "Meissen-Volkstedt" and such.
Hold in mind that what appears logical to you sounds in my ears like people claiming that a given
Roseville item was made "
by Boston-New York", plain nonsense. Wherever you heard it originally (oldandsold website?), please ignore it in future.
So no, that mark is not "Coburg", nor was it used by any factory located there. In fact it has nothing to do with Coburg at all.

Here is another reference,, this one defines as both down. two over like a tic tac toe mark or two down one over and one under !! Even more confusing when you get to thick or thin lines !!
The mark shown at the top there is an Asian repro; it's also frequently seen as 'VIENNA' or 'AUSTRIA' version.

The candelabra shown here was produced by the
von Schierholz factory from the town of
Plaue in Thuringia; shown mark type was used between 1890 and 1900. It can also be found with 'PLAUE' addition (used 1880-1906).
