Watch List notes:

Russia: State Bank USSR 1 Chevonets 1923 prototype, never issued, P.NL, with red overprint "ПРОЕКТ", serial number АБ0001. This one is different from the pictured notes in the Russian catalog with different guilloche at left. Paper thinning at lower left and right, pressed, slightly stained paper, some pinholes and printers annotations on back. Extraordinary rare item and surely unique.
