What does Limited Copy mean and how is it different from Numbered author copy (n to 25)

I admit it can be misleading but in fact there is a substantial difference!

The Numbered author copies (n to 25) are multiples of the original, retouched in oil, numbered (cataloged) and certified by the author. Once the series is over, they will no longer be made.

the Limited Copy is a copy of the original made like the original, often of different sizes, but has the same commitment as the original. Can be considered an 'Original version 2'
