I recently bought a Super Mario Bros. Gottlieb machine in amazingly good condition. I expect that as the years pass this machine will appreciate because a Super Mario machine can be considered a collector's item to some and there are so many of these machines in disrepair, but only a handful in as good condition as the one I am now the proud owner of. My question is this:
I want to install cliffy protectors to keep the playfield in tip-top shape, but does gluing down metal cliffy's affect the "collector's" value of the machine?
I know collectors can be very particular about what parts are original and what should and should not be found on an authentic collector's item.
What do you think?
