For 2010, there are many changes coming to Costa Rica. But one that was released yesterday, was the new emission of Costa Rican bills. It will start on March next year and it will affect the 1000, 2000, 5000 colones bills. There are going to be new ones like the 10000 and 20000 colones bills. The changes will be in shape, size and colors of the bills and it will be easier for blind people to know what are they paying with and also what are they getting back as change.
So, remember that next year there are going to be new bills on the market and do not be surprised that you are receiving different bills for the same amount. The change is going to take some time until all the old bills are removed from the market.
