This is what I found out. Most of this stuff (if not all) is from Archie Black. He would be the "go to" guy on this.

Titanic Slots. Tropicana. Giving away more than just jackpots, earn tickets redeemable for numbered, limited-edition Titanic coins.

Titanic Revisited
While the awesome Titanic exhibition at Tropicana has long been closed and all the related paraphenalia dismantled and removed from the property... and the gift shop associated with the exhibition has also closed.... the Titanic theme lives on. Trop has installed an island of ten slot machines which dispenses tickets for players to collect and redeem for attractive heavy bronze commemorative medallions with Titantic themed designs. The “sign” on the left, is sometimes posted on top of each of the ten specially equipped slot machines. The signs do disappear quite frequently as a result of souvenir hunters removing them from their lucite holders. Now for the “catch” ... so pay close attention.
For every 100 coins or credits played through the .25¢ slot machine ($25.00 in play action), ONE ticket is issued, via a dispenser located on the side of each slot machine..... similar to Skillo tickets in a kiddie arcade. It takes FORTY tickets to be redeemed for ONE commemorative “token” as they are called. Forty tickets times $25 in slot action per ticket, comes to $1,000 in quarters played to accumulate enough tickets for ONE “token”! To complicate matters further, there are FOUR different “medallions”, as I prefer to call them. To add insult to injury, read the fine print at the bottom of Titanic Slots rules as published to the left. If un-readable, it states, “Slot cashback will not be earned on Titanic slot machines.” I guess Trop management figures they are giving enough back to players in the way of these “tokens” so they are not obligated to give any additional credit for your $1000 and up slot play! No; I don’t claim to have played thousands of dollars in order to redeem enough tickets to offer these medallions to my subscribers.
