So sorry, Judi, for all the difficulty. But, with the information you gave me and the pictures I have, I can figure it all out. Thanks for your patience!
I am using the original pictures you sent because the ones above are not in a form that I can open here.
So #1 is a right facing woman, a bacchante, a female follower of Bacchus, the Roman god of wine. You can see the grape leaves in her hair. The earliest cameos frequently featured Roman and Greek gods. The setting is probably made of pinchbeck, an early form of gold plating, and the came was made in the last quarter of the 19th century. If this cameo is free of any corrosion or other damage, its current retail (replacement or insurance) value is approximately $150. If you were to sell it, you could expect to get the fair market (private sale or auction) value of approximately 40% of the retail amount, or $60.
The two cameos that depict women standing outside are known as Rebecca At The Well, which refers to the Od Testament story of how Rebecca became Isaac's wife, after giving a stranger and his camels water at her family's well. The were both made during the last decade of the 19th century. The rectangular one, if it is in excellent condition, has a retail value of approximately $160 and a fair market value of approximately $65.
The oval Rebecca cameo is damaged and missing the pin stem. Its current retail value is approximately $50 and the fair market value would be approximately $20.
The last cameo is a Victorian slide on a bookchain necklace. It is also set in pinchbeck and the figure is very small. It is most likely a generic woman figure, and was made circa 1870. If it and the chain are in excellent condition, its current retail value is approximately $200, and the fair market value is approximately $80.
I hope this answer has been helpful to you Judi. Again, my apologies for the delay.
