Dear Collectors!
In 2013 Kazakhstan issued a set of miniature coins. With one standard coin: N#48794

I have noticed that these coins have not yet been added to the catalog, so I wanted to add them. However, I am not sure what category they fall under. They are miniatures (thus have smaller diameter and weight) and according to the set are not legal tender. I was thinking they should be considered as “Collector coins”. But maybe they better fit the definition of some kind of exonumia. So I wanted to ask for the opinion of other collectors to reach the consensus opinion.
Thank you for your answers!
