I recently purchased a bottle at a flea market and am trying to find it's value. It is an amber colored bottle about six inches tall. Jen sal is embossed on the bottle. It still has a label but it is wearing off around the edges. It appears to say anti hemmorhageral septicemia serum. Like looked it up As much as I could find on Google and it was a vaccine for horses, cattle, buffalo, sheep, swine, and fowl. It has a serial number, an expiration date, and a veterinary license number for the person who prepared it. I found on on eBay that is listed with a pricetag of $750.00 from a reputable seller with good feedback. His bottle does not have the label or cork. Mine has label, and the cork has fallen through onto the jar. Someone please help!!
