If you pay retail price for Walkers you probably cannot get your money out of them when you sell them. For common Walkers or ones that are in less than good condition you get about melt value. If you bought a 1918 Walker and you can read the date then $8 is a good price indeed. If you look at Walkers before 1929 they tend to be pretty expensive in EF and above condition. One thing for sure is that it is pretty hard to find them in MS-60 condition and beyond AU the prices go crazy. 1921 through 1921-S just in EF condition will cost you about $7000. I do believe that completing a set in any condition and then improving them to the best condition you can afford will pay off if you can wait and not turn over your collection too often as in doing a lot of trading to make small profits. You could spend many years and thousands of dollars improving a set of Walkers. The same goes for most sets of the early 20th century and without question for 18th and 19th Century American coins. The sky is the limit for Morgans and gold coin sets. The only gold set that seems to be able to be filled these days is the Quarter Eagle Indian Head. Other gold sets have certain coins that are just not available because of melt downs etc.
