I appreciate you having a look at these.  They are unedited, right from the
scanner. You can see them at:

Moreover, the samples here are so small that it is impossible to really
appreciate the quality and do anything useful. You should scan at 300dpi
at the very least.
    

I agree with the comments and would add that if you really want to
achieve the best possible than scan at 600dpi and take it from there.

I had the same problem as you, scanning more than a thousand family photos and doing some restoration on each of them. When dealing with photos that were on a textured paper, and I had a lot, I used a plugin called 'GREYCstoration' to remove the texture.

It is a complicated plugin and I had to do a lot of experimentation to produce acceptable results. But two details that I do remember at this time was to scan at high enough resolution so the texture is well defined, I recall 450 dpi in my case and do not use an unsharp mask until the texture is removed.

The plugin has been part of and superseded by G'MIC from the same people and can be obtained at

Look in the enhancement section

Good Luck

Lawrence
