Getting ready for a sale this week , getting rid of bottles and jars I have had for a good many years . I have a half gallon amber Lightning fruit jar I have had for a good thirty years guessing . It looks like the number 417 on the bottom of the jar . I did a search on eBay with no luck as for finding one to see what they were selling for . My question is , is there a half gallon Lightning jar with the number 417 on the bottom , wondering if I am reading it wrong , the embossing is a bit light on the end of the number in question . Do the numbers have a lot to do with value of a jar or are all half gallons sell in the same range ? I see that colors as for yellow amber and so forth make a difference but this one looks like a regular amber color to me . Sorry for no pic , not possible at this time . Thanks in advance
