Carlos:

I think rare is in the eye of the beholder and there are no clear rules.
  This has to be measured in the context of your collection and your
institution's purpose.

One suggestion, however, is to create a collection of interesting items
discovered during your weeding.  How about a 'Map Example Collection' or
'Printing Process Collection' that addresses the maps that you feel are
significant into a thematic grouping?   This collection could be a
'bucket' into which you put potentially interesting things until you get
some time to research further.

Your weeding process would be able to continue, thereby satisfying some,
and interesting specimens from the collection would be saved, thereby
satisfying others.

I posted the inquiry about how to determine if a map is rare due to a
possible weeding project in our maps collection.  I would really like to
know how to identify such maps.  We are a Federal documents depository
and we have quite a collection of maps.
For example:
--Are the */Geologic Atlas of the United States/* that were published in
the late 1800 and early 1900s be considered rare though quite a few
depository
       collections may have them.
--How about the early 15 minute series maps. are they also considered rare?
--The other day while going through the collection, a student worker
found a USGS map that included a black and white photo image (looked
like a satellite
       image).  Well, the map had the following phrase printed on the
lower right corner of the map: */Experimental Issue/*.  Though not old,
could this be
       considered rare because it was the first time they tested
something new?
We don't want to remove something that could be valuable.
