Victorian Penny Stamps Inherited - Opinion On Value

Have a huge collection of old British Victorian penny stamps inherited. Would appreciate any advice on value. Here is first lot. Thank you!

Ideally, we need a scan, rather than a photograph, but these are likely to be worth very little. Several are damaged (missing corners etc) and all have been cut near to the design. The first thing that people will look for on these early issues is the presence of four clear margins around the design - the 1d black, for instance, has only two.

As GeofHa has stated, these stamps are, on first look, of poor quality and probably not worth a lot. The prices for Penny Black stamps of this quality (less than 4 margins for instance) has fallen quite a lot in the last few years. Even a Penny Black with 4 margins from a more common plate can be had at prices starting at £80... probably less if you look around.
The first three stamps might be worth plating and, who knows, there might be something of some value if uncommon or has a variety but any detail cannot be seen from your photo.

Thank you very much for your valuable input. Much appreciated
