Mexico - customs requirements [solved]

Dear users,

does anyone have experience of bringing coins in Mexico or from Mexico?
I wonder what restrictions may apply, especially with regard to coins of silver?

Thank you.

Are you planning to travel with over a kilo of silver?

I have travel with large amount of coins from many countries and not a problem so far (Silver / Gold)

From Mexico my only experience was two years ago and took about 1 kilo of their circulating coins back home without any single problem... I took domestic flights and then international flight out of Mexico City.
