Hello,
I would love to know if anyone has noticed any differences in the mintage between the years 2023 - 2025 on the Swiss Proof Sets.
These are just sample of 5 Swiss Franc coins from a Brilliant Uncirculated Proof Set coins over those years.
I wandered if the “scratched background” both in 2023 and 2024 is a part of the design or some error.
These “scratched background” design appears on all other coins in these sets on both sides except the 2025 set.
The first coin is from 2023:

…the second 2024:

…and the third 2025:

Thank you,
Yair
