Brian,
I would agree with the observation that both you and Joe have made. That is, that a black EM visor is MUCH more common than an SS coffee can kepi.
As for price, my belief is that the black EM visors are uniform enough that most collectors can tell originals from fakes (although the fakes are getting better all the time). Since this is the ONE piece of ss headgear that most collectors feel comfortable buying as an 'original' item that they can trust, they are willing to put up to $5,000+ into one.
Although an original black kepi is much more rare, most collectors have trouble trusting them and thus are not willing to put big bucks into one.
Just my opinion.
Doug
