Trying to order from eBay.

Why not take all your foreign money to the bank and have it exchanged for dollars?

The trouble, with this, as with the others, it has almost no value. In exchange.
It has been replaced twice since 1987 each time the value goes down extremely

On February 15, 1988, the 2nd córdoba was introduced. It was equal to 1,000 1st córdobas. On April 30, 1991 the third córdoba, also called the córdoba oro, was introduced, worth 5,000,000 2nd córdobas

so, your 50,000 was worth 5000 of the 2nd issue, and then worth less than one on the third issue.

for sake of conversion, if it was worth one cordobas, then it would be worth about 4cents US.
