Mayan dollar scam in Mexico

How it works:

• This is a made up currency which vendors use to trick you.
• For instance, a vendor offers a gemstone or carving for $3. You pass him a $10 bill, but he only returns $1 and claims it is 3 Mayan dollars which is equivalent to $9.

Places to beware:

• Playa del Carmen

What to do:

• Clarify the currency before purchase. Ask for your money back if tricked.
