From the looks of the background(if this is your Shop) you could probably advise many.I have never seen either of these pins and they look cool.The Chicago Coin would be desirable to restore due to its Sports Theme to working condition but parts availability may be problematic. The Williams to me would be more desirable and the parts could readily be had(I can live with flawed plastics and honest wear) as long as she plays crisp.
I look forward to your input,looks like you have it going on with vintage coin-op and have been for awhile.
