I am new here, so I hope this is in the right place. I acquired this bottle from a garage sale. It says Jayne's Expectorant. Janye's Tonic Vermifuge. Etched on the glass it says Jaynes on one side and Tonic on the other . On the back, it is etched to say - Good for mother and child. It has a label on front. It is clear green. The bottom is curved in and you can see a letter "C" in a circle. I need to know when this is from (approx year or time frame) and what the approx worth may be?? any help is much appreciated. I have NOT seen many like this one - so wondering if it is RARE? and worth more?
