Russia 5k 1864 Double headed eagle color ( error ) ??

Could you please elaborate a bit on why you think they are errors?

Peter

I think it's a error in color .

Same, there are four nice looking stamps. Which one has a color error? Please be a bit more specific.

Peter

I do have these stamps in my Russia Collection.....please elaborate - Thanks same -

5 kop. stamp of this type (with Roman "V") can exist in 4 different perforation varieties, first two issues without watermark, the last issue with "wavy lines and letters" watermark on laid paper. In all these cases this stamp can be only two-colored (black frame and lilac background); Solovyev mentions two minor color varieties, black on light lilac, and black on violet. No Russian specialized catalog, including the most detailed, Mayorov's, lists Roman "V" type 5 kop. stamps in single colors shown on your scan.

The only possible conclusion is that these are newprints (reproductions) or essays (color trials). Since frames and backgound of the stamps shown on your scans were apparently printed separately, and their perforations are typical of the first type (narrow spaces between the perfs and the frame), these could be essays or color trial examples — but only a careful paper analysis by an expert could confirm this. If these are original color trials, they may have a substantial value for collectors.

However, especially if the paper is very white and glossy, these could be clever modern photo copies (reproductions), in which case they are just a curiosity.

I think 1866 trial color proofs .

Could well be Exhibition reprints/reproductions as mentioned by tvorog. Very hard to imagine them being color proofs... being perforated is unusual and would be extremely rare proofs and there are four of them !
