Skilling coins found in my collection from when I was a child wondering if they are worth anything

2 rigsbank skilling 1818
2 skilling species 1831(very heavy)
Half skilling 18??
4 skilling species 1825
4 skilling 1842
6 rigsbank skilling 1813

nice collection, yes they have some value.
picking out ranges of values out of Krauss, depending on grade, which I am not qualified to give -
Norway
2 skilling species 1831 KM# 295 $15-30
4 skilling species 1825 KM#298 $10-30
4 skilling 1842 KM#311 $5-15
Sweden
1/2 skilling KM#596 - illegible date maybe $2
Denmark
2 rigsbank skilling 1818 KM#689 $10-20
I believe the last one is either Kingdom of Denmark, Norway and Holstein KM#Tn1, or Norway KM#282
which an expert might be able to distinguish, but i do not know the differences to look for,
6 rigsbank skilling 1813 $20-40

Thank you for your quick reply Mr Midnight I appreciate the information.
Will have to now find the rest of my coins as I remember having loads as a kid. Funny what you find when you get a skip to clear out the garden and house ?
