Acetone, which you should be able to get from your
     local pharmacist, or perhaps at a paint store, will
     dissolve glues of the "airplane glue" variety.  The
     only problem will be the ink in which the specimen
     number is written.  In my experience it was standard to
     use India Ink, which is a water base and would not be
     effected by the acetone.

     You should try acetone on one specimen to see if it
     will do the job.  Start slowly and use it sparingly
     until you see how it goes.  Good luck.
