Thank you so much, usually I take a look to the rood if more vertical is in circle if more oblique is oval. If I can not see the rood I take a look to the shape of crown .. if the outsider lines are continue...smooth... is oval if I see no continue lines an "rustic" not smooth shape of the crown I think in circle.
if I can see just the "feet" of the crown , if they touch or the seems to much near to curve lines is for me in oval, if they does not touch and distant in unique way from the curve lines frame I count as circle.
I would like to show to you others.
I think 15 kr circle, 20 so problably in Oval
, while, 25 in circle ( I have other 2 minimum cicle ) is in circle but have a problem infact the watermark ruin the design, seems, and then I ask to confirm. if was for usury had to be all above the stamp instead is just on watermark lines, i'm in error?
