Hello all,
Ive
inherited stamps that Ill be looking to sell. Theyre roughly 6 albums. I took this to an appraiser (if thats the right word), who told me id be looking at 600-700 euros worth of stamps. Although I would agree with him that most are not worth more than their denomination, there are a few olders ones that I think would be interesting. My understanding of stamps and how they should be valued is very limited though. Could you share your thoughts on the below sets?

Above dates from 1850s. Given that all 6 albums were values for 600/700, I uploaded these somewhere online for bidding to start from 150, to which I got 1 or 2 concerned replies that that was not very realistic. 1 person said the catalogue value was close to 7k eur….?

The above are from 1881, combination of stamped and unstamped. Its on granite paper, which I was able to distinguish by the red and blue fibers. Seems to be highly valued by Scott??
I know valuation depends on a lot of factors, such as actual condition, color, margins etc, as well as 'what one itself may think its worth'. However, can somebody help me with a very rough indication of what a reasonable selling price would be?
Many thanks
