Excellent finds! These are actually coins on my bucket list in America. In the mid 1800's the lumber barons formed a land company to divest themselves of the land that had been logged. Thousands of Swedes, Finns and Poles were swindled into buying farmland that was stump covered and sandy. Not enough trees left to even build a house. But people in those days dealt with adversity much better. The soil was perfect for fruit orchards and most thrived.
It is very rare to find silver coins pre 1875 ish here in Sweden. So anything pre Oscar II really makes your heart pump! In 6 years I've found hundreds of small silver coins from 1870s-1968 but only about 10-20 pre 1875.
