Hello XXXXXX,
The value of a ticket to the Dallas luncheon in 1963, could be worth anywhere between $200-$800 given the condition of the invitation. Also, it would be worth more if it were accompanied with an envelope with an address or company name on it. The more specific information it has, the more it will be worth. As with any modern memorabilia, value is in the eye of the beholder. I have personally seen memorabilia bought back by celebrity estates for thousands of dollars. You may want to ebay it as an auction to get a better idea as to the market value. The value that I gave you is a very "open" number. I would need to see it to give you a more specific value.
Good luck,
