In Morocco and other parts of Africa where the old phenolic beads have been worn for a couple of generations they are considered to be amber so it makes sense that there would not be a price difference.

The visible differences between old and new phenolic beads can be difficult to determine. However, if you look carefully, the old beads should show some wear, a more accurate "color" with more "depth" and will be a little heavier weight. Cracks and internal fissures are a good sign BUT many old phenolic beads do not have these.
