At the start of 2013 Hasbro decided to retire a token and introduce a new one. This was done through a poll on Facebook where you had to choose which token you wanted to keep and which one you would like to replace it from a robot, a ring, a cat, a helicopter and a guitar. In the end the iron lost out (the smallest token which you could hide behind bukldings) and the cat won. A special edition version was released exclusively via Target stores with all 13 tokens which were sold out very quickly.
If you look at the dates on the boxes when they were printed, they are dated 2012.
July 2013 sees the first versions in the shops and online with the cat instead of the iron, and with a totally new box design. And already there are two slightly different versions depending where you purchase them from.
These photographs are from the version if you buy it from the Hasbro Toy Shop.
These photographs above are from the version you will get if you purchase it from Target. Just slight differences, but there.
2014 sees a new look to the USA box front as the back is virtually the same. The cat is now prominently on the front of the box with the dog. Otherwise it is basically the same and the same code of 00009.
In 2016 and Hasbro introducing a new logo, the original USA version was released with 16 tokens with different ones from throughout the history of Monopoly.
Hasbro also introduced this version with a square box version. Code: C3888
