Off-set impressions

I have two South African coins that have offset impressions (both 10c but from different eras).

a) Can these be added to my collection here on Numista ?

b) Can they be valued ?

Hello 🤖

Without pictures, it will be very difficult for anyone to help you. Could you please post clear pictures of each side of your item?

Unique mint errors don't get there own lines. Just add them to there respective year line and add a comment.

Nice errors!

I could not find many South Africa error coins that have actual sale prices.

Yours are worth more, because the % off center is greater.
