This work wouldn't have been possible without the collaboration of a good number of friends and organizations which have contributed with their pictures of coins, information and ideas.

A list which I hope will increase in the future with more contributions. For that reason, I make a call to all those who can send me the picture of that coin, or coins, they have in their collection. I'm looking forward for these pictures (e-mail).

Their dies will be identified and included in the registry, detecting other pieces with coincident dies with your coins and including them in the minting sequence of the series, fact that will represent an added value for that piece in your collection.

I want to express once again my deepest recognition and to thank to all who had helped me, and without any doubt, they will help me in the future:
