Kennedy Half Low Ball Question

I have a clad low ball Kennedy half I found while roll searching that has the date worn off. My question is without a date will the value be more or less than if it still had the date present? A few more years as a pocket piece and this one would only be a slick piece of metal. I'm not to interested in low balls so I was thinking about listing it on ebay at a later date. I'd also like suggestions from low ball collectors as to what a good starting price would be and what you think it's final value would be. The coin has nice eye appeal, if low balls can have nice eye appeal.
