Hi, I am not 100% sure.
But I will try to explain.
The stamp is: 4 Millionen Mark 1923 Deutsches Reich
Catalog: Michel.-Nr. 316
1. BROKEN ROSETTE ON THE LEFT( PP 8 ) ordinarry
2. Full coloured horn (?)
4. Thickened (something like PP 11?)
6. Thickened line
8. Coloured- originaly free space
I have naive hope that this combination is rare, but there is a lot of stamps from this time. And I am not an expert for this category. So, there is a chance, that It could be some ordinarry full deformation, with no value.
Thanks for comment :)
