Less than 2-3% of the T204's are found with TTT backs. When old time complete sets were offered in the 1990's-early 2000's(which was very few) they would normally have 3-4 cards in the entire 121 set with TTT backs.
At this time only about half of the T204's are verified to exist with TTT backs. There is debate about whether all of the subjects were made or not made with the TTT backs. I feel they probably were and so scarce due to low production and attrition that the other half have not yet been found. O'leary is one of the confirmed subjects.
