Hand Hellers - Schwäbisch or...?

Hello,
I believe these are Hellers from Schwäbisch Hall but I can’t properly identify them as there seems to be a few different types that don’t look very different. Can anyone help me out?

#1:


diameter: 15.5mm
thickness: 0.1mm
weight: 0.41g

#2:


diameter: 16.8mm
thickness: 0.15mm
weight: 0.50g

They look indeed like 'handhellers'.
They are manually hammered, so a lot of variations are possible
