Response to Doves comments   Dove thanks for your comments on my changes and refutations  I respond to your points below   Dove writes  The recent edits by  have been reverted because they removed content The arguments given above are highly unconvincing To begin with   there seems to be a misunderstanding as to the Spanish currency There was never a currency called the peso used in Spain All arguments based on the   assumption that there was are spurious Second there is clear evidence that the Mexican peso was an important trade coin in Asia and was adopted in   several states as the basis for the States own currencies  My edits did not remove content they removed unsourced and in a few cases obviously wrong information  It is not enough to call my arguments unconvincing if you would argue the contrapositive you must do so  First of all I note I never claim that there was a currency called the peso in Spain  You need to reread my arguments because if you think I made that claim you obviously didnt carefully read them in the first place  The claim that the Mexican peso was the basis for US state currencies is obvious false because Mexico did not exist as a country with its own currency prior to the creation of the US Dollar   Dove writes  The statement above When the HKD was established its basis was in grams of pure sterling with  HKD worth  grams of sterling valuing it at    shilling is nonsensical Clearly there was a link to sterling but this does not disprove that the Mexican peso was the original basis  As to the Japanese yen what is a gram sterling Yes there was a peg to the pound sterling but that again does not mean that the Mexican peso did   not serve as the origin for the yen  My apologies for my comment on gram sterling I assumed you were familiar with Imperial Measures and therefor would know what a gram of sterling silver was  The HKD and Japanese Yen were clearly based on the Shilling which was worth one gram of sterling silver  This was done at their conception which dispoves the Mexican peso as their original basis   Dove writes  There is a need to clarify the events of  which is why I originally asked for a citation Im afraid that the link Jolliette gave does nothing to    say one way or the other as to the origin of the first US dollar  Actually it does say one way  As the claim in the article is that this very law instated the Mexican peso as legal tender and yet the law does not in fact state that it disproves the claim that the Mexican Peso was made legal tender by this law
