Scott Catalogue show Denmark watermark 111 with a flat oval
The Michel catalogue doesn't, so I don't think that is a definitive marker. Look at the lobes of the crown -resembles Wmk 111 rather than Wmk 112.
Also the size (Small vs large) of the Wmk is important.

And aren't your examples a probable imperforate (Scott 6 - Wmk 111) rather than a rouletted 11 (Scott 10 -Wmk 112)?
But, you could always send it in for a cert if you are willing to spend money.
