Personally I might grade this coin G/VG so book value estimate maybe $40-50.
Selling prices are often lower than book value, personally I set them maybe 30% lower, so if I were selling would set price maybe about $30-$35. Others might grade and price this coin differently.
Reverse is more corroded and worn and thus the overall grade is lower, I'd say VG. Based on Swedish Myntboken 2017 (coin catalog) the value is somewhere near 30 USD.
