Newspaper Medallions--NFL Activa

Is there any trading going on with the NFL medallions which are
purchased
by coupons in newspapers. Certain teams like the Packers, Bears,
Vikings,
Steelers and Colts are obtained locally. A national league wide
collection
of 30 is going on in USA Today now. The local medallions can be a pain
to collect because they are obtained one day at a time, retailers run
out
and some have no means of collecting at the end of the run. There is
at
least one error in the Packer collection. At times they appear on
Ebay.

Does anyone think these may be collectible or that some may be scarce?
