If you’re planning on traveling to Costa Rica  any time soon and you intend bringing the notes left over from your last trip, be aware that the old 1,000 and 2,000 colones (¢) bills issued prior to mid-2011 are no longer legal tender and that after December 31, 2012, the ¢5,000 and ¢10,000 bills will also cease to be accepted for everyday transactions.
On August 27, 2012, the Banco Central de Costa Rica  introduced the final denominations of a new family of banknotes, launched on June 20, 2011, with release of the ¢1,000 and ¢2,000 notes, plus a ¢20,000 bill. Introduction of the new “family” of six banknotes coincided with the 60th anniversary of the Banco Central, in San José .
The old series notes of any denomination will cease to be legal tender on December 31, 2012. After that date you can exchange ¢5,000 and ¢10,000 bills at banks for the equivalent new currency (but after May 1, 2013, only at the Banco Central).

The new notes  are striking for their bold colors and exquisite designs. The front of each of the six denominations depicts an important historical figure who has contributed to Costa Rica’s democracy. The reverse sides depict the country’s biodiversity, representative of six ecosystems, with iconic species of the ecosystem depicted.

High-tech security features…
The notes, which were printed by French company, Oberthur Technologies, are also about as high-tech as currencies come, with state-of-the-art security features to guard against counterfeiting, including:
• The face of the historical figures plus the printed denomination are embossed in 3-D.
• A hidden image of the historical figure is revealed to move in a transparent section when the note is held up to the light.
• Elements on the note, plus the security thread, change color when the note is tilted.
Made of a fabric-like yet dirt- and humidity-resistant polypropylene material that’s three times as durable as cotton fiber paper notes, they also include braille features for the blind, while the bills also uniformly increase in size according to value.
Oh, and don’t expect your taxi driver to have change for a ¢50,000 bill. It’s equivalent to US$100. In fact, don’t expect them to even accept anything above a ¢5,000. Many Costa Rica vendors are simply too concerned with theft, never mind the ability to make change for high-value bills.
