I picked up an 1878CC Morgan Dollar today from my local coin shop and it is encased in a slab from Global Certification Services, Inc. I did a bit of research and discovered they were a 3rd party grading company that stopped operating several years back. I understand there was a thread about this company on Coin Talk back in 2007 (http://www.cointalk.com/t28832/) but I would like to ask a different question. I was curious if this slab is detrimental to the coin's value or if I can crack it out of the slab without regret. It's a pretty nice display, but it doesn't feature a grade or serial number. Any thoughts?
