Interesting conversations. Thanks all.
Just to let you all know I left it alone. I have 15 morgans to go and may never get them all.
I have another thread about cracking open a a SAC PF69. Much much less expensive coin that I did crack to make the set. Being a proof its more susceptible to environments in a dansco than in its sealed case. At the same time its not as bad as cracking a MS69.
