Soviet Inissued Naval Rank - What's something like this worth?

[pastfinder]

I've had this rank for a few years. They are matches sets, and all but one are still stitched together. I'm planning to sell them/trade them but have no idea what something like this is worth and wasn't sure if this is more of a marketplace thread or an uniform/insignia thread.

Anyways, here they are. The gold wire is more or less flawless on these. The insignia is pasted to thin cardstock.

These are Soviet navy rank sleeve insignia.

Upper single wide stripe is for captain 1st class (naval colonel)

4 stripes in the middle of lower insignia set - for captain 2nd class (naval leutenent-colonel)

Other rank is for Admiral of the fleet of the Soviet Union. But I think that they are fake (new-made).

Stars are the parts of captain 1st class and captain 2nd class insignia sets.
