Today, while watching my fish tank I pulled up mynebay app and started scanning the new camera listings.
Long story short, I ran across this 1.5/7.5cm Biotar that seems to be early and uncoated and it good condition. Not a bargain at $850 but I figured it is a good deal.
I was wondering, can anyone tell me how early of a Version it is and which version it is for sure? Also, is it for sure not a counterfeit?
The serial number is 2530923 which strikes me as pretty low as I’ve found plenty of 26xxxxxx examples.



Also, does anyone know how much this would be worth, assuming it’s in good condition?
Cheers.

Looks genuine , I never seen or heard fake one from this lens, no Russian cheap similar lens exists, so hard to fake it.

The closest Russian lens is a Helios 40, which look very very different.
Helios 40 is a copy of the late 75mm/1.5, they could be copied, but their prices are not that far apart.
