1869 Prince Karl I Romanian Stamps Question

I've got a simple question regarding some old stamps that are cut from a book that they were glued to (from my great-grandmother). Do those stamps still worth something or not? In general what would be a price drop because of it?
I know that the first row stamps are 1869 Prince Karl I.
Also I can't identify if the first one is blue, ultramarine or indigo.


Thank you,
Basilis.

Opinion.
Top 3 are Sc#38, 40, and 42
If genuine I pay around 25% scott cv CV$32 so $8 each
First one is blue.
Depends entirely on the mucilage (gum) used to stick down,
and whether it is water soluble.

All have fairly ordinary pmks.

I would'nt care to advise on selling.

Your last 4 Scott Type 13, need to find a Wmk and Perf guages. Tinted paper?
The 5 and 10 bani, look in good shape, the higher values, smudgy Pmks
ID is crucial before appraisal.

1869 Quoted value $300 Listed for $40
