On September 6, 1995 Cal Ripken Jr. broke Lou Gehrig's record for consecutive games played, 2131. It was no secret that this was going to happen, All he had to do is show up for the game, and because of this the Orioles were able to print up commemorative programs & tickets for the game.
The commemorative ticket "books" for $90.-$100. and the Game day Ticket about $200. The reason I quoted the "Book" value is because this value reflects the price of theses collectibles when it was a hot item, and everyone wanted one. Now 12+ years later most everyone that wanted one has one. Demand is down, the dust has cleared, and two tickets for this game recently sold for $35. on eBay. A good buy? Yes. I would put the current value at about $35.-$50. a Ticket, and in the years to come as more collectors join the market they will rise in value. Back to the "Book Value" price. A ticket Stub might sell for half that price.
