Looks like the conversion and refurbished bike was a Murray-built girls Sears Elgin, from about circa 1937–SC or 1938–SD; and the date code stamps would be on the bottom bracket crank hanger; ~85 years old.
One might do some market research by looking at the bicycle, and searching for the price of each part and accessory; (but do not expect that the price for the whole would equal the sum of the parts).
Also worth mentioning is that the price for the whole would not equal the sum of the parts).
When looking at the prices, consider whether or not those prices will afford you a fair profit, when considering the costs, including time.
If the goal or objective is to simply get rid of the bike, then lower prices than those not selling very fast may help move your stuff.
Consider the effort to disassemble, photograph and list the piece parts for sale and to box and ship, etc., cost of shipping small, medium and large items, and if that is what you really want to do, or not?
