Ran out of room for this thread title;
Expertising and identifying varieties - can you gain the skills from scans or is having the genuine article in front of you essential?
The reason this thought came up is that I finally won an auction of early Finland that supposedly contains examples of both the laid AND ribbed paper varieties. I didn’t have enough of these to be able to tell the difference confidently.
So I’m curious - just how well can we learn to identify these types of varieties using just high definition scans and, if not, which issues in particular really need to be in your hand to be able to identify.
A good old example of an issue that I think is impossible to identify or learn to ID by scans are the early Irish overprints blue/black and black inks. I can only tell the difference when I hold the stamp at an angle under good light. Then the bluish tones become noticeable.
Another example of must have in hand would be paper thickness. No scan will give you that information!
One example that is extremely easy to ID using a picture are the Finland perfs. All four types of serpentine perfs are perfectly simple to differentiate just by seeing a sketch.
Would love to to hear your thoughts on some examples of issues that you really need to hold in your tongs to be able to identify.
