Oh, I love worry dolls. I keep a string drapped from a shadow box, and arrange worry dolls on the string to make them look as though they are climbing up or down the string. They are cute... lol.
I also used to have a ring, which was silver, and had a gem inside that resembled a green eye. I guess it coudld be seen as an evil eye. It always reminded me of something from the movie beastmaster... That book with the eye.
As for the bag, with the little dolls, charm and penny, I haven't a clue what it could be. It could be a charm/spell bag of sorts. But then, it could just be a bag. If it were a charm bag, I think the dolls could of possibly represented someone of a certain significance for the person who made them. The penny might be seen as being for luck or money. Though Pennies are also made of copper, which is suppose to be a very high conductor of energy, maybe that could of been of significance to the person too. And the locket is usually something used to store very precious memories in.
I have also found some interesting things before. Though not as curious as the bag and little trinkets. I once found a ring that happened to have my initials on it. I still have it. It has an opal gem, which also happens to be my mothers birthstone.
