I found this as a tourist highly fascinating and really worthwhile. Tickets for foreigners are $5 usd, but the whole museum is filled with English displays that tell the story of how money and history intertwine all the way from the Khmer empire to modern times. They also answered a few really interesting questions I had when coming to Cambodia for the first time, such as 1. How the Cambodian riel came into existence and it's high rate of inflation over the years. 2. what the very first currency was in recent times, and how that was introduced during the French colonisation. 3. The difficulties faced living in a society with no currency, something the Cambodians had to deal with over and over again. 4. Why and how the dollar was introduced. They also have dozens of videos depicting real life pictures and videos of the lives Cambodians faced in the 20th century, alongside how money was affected by the history. Alongside interactive displays at the end, and a place to sit and listen to modern economic challenges the Cambodians face today, including the rise of tourism, it took me a good 2.5 hours to explore. I'd highly recommend it to anyone who wants to experience Cambodian history through a different lense!
