John,

As a collector of Grand Opening I also collect the Inaugural Cruise and the Maiden Voyage chips as such. I consider them as 'one and the same' connotations. I even collect and categorize a chip issued on the beginning of business operations of a casino as GO, i.e. the chips with year date alone or with a month, day and year date even without the 'Grand Opening' statement.

Thanx for your comments.
