I would probably put this in the $25-50 range for a retail price - meaning at a show or perhaps a buy-it-now on a venue like eBay.
This auction provides something of a reference point:
https://www.ebay.com/itm/Lot-of-Eight-8-Labeled-Quack-Cure-Medicine-Bottles-For-Children-amp-Babies-/224320103395
This grouping sold at about $40 each...I would argue these bottles are a bit older, and a bit more desirable. Collectors pay a fair amount of attention to the type of bottle so a "cure" or "remedy" or "bitters" are going to be valued more than other categories. Medicines that contained now-banned substances like heroin or laudanum are prized.
I hope this gives a bit of context for the valuation and is helpful.
