Inverted coins.

Greetings! I have inverted coins. I ask the professionals to look. Maybe you know the approximate cost?

Could you tell me your process of how you search for coins on Numista?
There is much information on a coin page that might interest you and answer a lo of your questions.

By the way this 180° die rotation is called 'coin orientation' and is the norm for this type.

Thank you for your reply! I haven't figured out the site yet. Newbie here. There are kind people on the forums who can suggest or give the necessary information. I used similar sites only in our country. We consider such turns to be a marriage. I am not a numismatist, so if I write incorrectly, excuse the newcomer in advance. Thank you for your kind advice!

No problem being new but I just don't want you to ask for each and every coin the same question if the answer often is on the tip of your fingers.
Just type for this example '1948 5 confoederatio helvetica' in the search box on the top right or if you click on 'coins' in that search box and you will find your coin Search query.
There is also a Numisdoc page were you find helpful tips on the use of Numista.
Like How to search a coin in the catalogue (but this one seems kinda old and we should update this )
