1. Matrix hubs ("positives of") and "working dies" ("the negatives") for the production of of Bolivian of coins of the eighties of the XIX century at the mint in Potosi (Bolivia).

 

2. Matrix Hub ("positive") for the formation of working the die of the reverse coin of 1 centavo (Bolivia) without the last two digits of the date.

I emphasize:

 

1. Formation of the working part of the stamp, in the process of slow plastic deformation of the tapered portion of steel billets, occurs once.

 

2. No repeated die hubbing, offset, doubling of contours of letters, numbers, pictures here and there can not be.

 

Against what I have said above there is objections?
