50 Pesos

Mexico's shift to polymer for the 50 Pesos came as part of a broader reissue program that brought Guardian® substrate — manufactured by CCL Secure — into the Banco de México's production chain. Notably, this note is printed in-house at the bank's own facility in Mexico City, one of relatively few central banks worldwide that operates its own printing works for polymer issues rather than contracting an external security printer.

The Guardian® window integration allows design elements to pass through the transparent zone rather than simply framing it — a more technically demanding approach than earlier Mexican polymer experiments.
