The following patterns were available in both a BU pack and a proof set and this is mentioned on the pages.
Only the first 2 (the 0.01 and 0.02) have the option for the proof, the rest have the BU only listed. The others should have the option of the proof coins added.
In addition to this, N#240510 is the €5 coin that was available in the 9 coin proof set (not in the 8 coin BU) but it's not marked as being a proof coin and does not include the information about being in a set.
I do not own the proof set (I have the BU) but for reference, it is this one https://www.ebay.co.uk/itm/284543354474
