Have a nice weekend and no stress.
Hi and my opinion is that Otakar Spaniel - the sculptor and creator of most of our coins did not show a specific botanical type of wheat (for meal flour), but ears of wheat as a symbol.

It's probably one of these types - but I don't think even a botanist would specify:
Plain wheat (Triticum dicoccoides Körn.)
Two-grain wheat (Triticum dicoccum Schrank)
Timofeyev's wheat (Triticum timopheevi Zhuk.)
durum wheat (Triticum durum Desf.)
Triticum turgidum L.
Polish wheat (Triticum polonicum L.)
Yes, the linden tree and its twig is a symbol:

Perhaps I can only add that these days these coins flew steeply upwards.
Only now am I writing again - simply "Yes and No". but it's me.
