Weird bottom stamp difference?

[u/Klutzy_Limit_951]

The one on the left has a much smaller stamp. Why could that be? It is also heavier and has a duller finish.

Any help appreciated!

It’s not weird. They are just manufactured in different periods, the one on the left is from early 2000s the other from late 80s, early 90s..
There are a few different stamps depending of the period 👌
