A neat 1870 CC Dollar Story

Ok, here's the deal. My great grandfather was a butcher in Carson City, having moved there in 1859. His shop was the Eagle Market. His name was Matt Rinckel. Wife was Marcella. Matt was known to almost all as the town was small and Virginia City was the largest city in the area due to the gold/silver ores found there (the reason for the mint). Matt fed many a miner. He also owned the local racetrack and helped relieve the miners of those hard earned cartwheels.
Being a fairly wealthy man he hob-knobbed with them all. From Governor Blasdel to Abe Curry to Sam Clemens (the home next to Matts was his). The mint was a big event in CC history and Abe was very well aware of this. Opening was delayed but eventually the Philadelphia mint decided that 1870 was the year and shipped dies with that date.
The dies arrived in Carson City in December of 1869. Abe wanting to test the process and the equipment began test runs with the new dies. After adjustments and being fairly satisfied with the results he minted 3 dollars. He had them all engraved with the initials of the persons he gave them to. MMR to my great grandfather and grandmother (Matt and Marcella Rinckel). The other two were given to Gov Blasdel and the President of the United States, US Grant.
The way it happened was this: At noon on a day in December, Abe stopped by Matt and Marcella's home on the corner of King and Curry. Marcella answered the door and Abe said: Marcella, please hold out your hand. We have begun the minting of the finest dollars ever to be minted and I give you this dollar so that you will never be broke. This is the first dollar ever minted in Carson City.
Now Matt came to the door to see what was up and they all went to the kitchen and discussed the huge economic help the mint would be to Carson. Marcella showed Matt the coin. Matt died in 1879. Marcella lived into the 1930's. Together they had 5 children. One daughter, my great aunt Louise, ended up with the dollar. Marcella had carried it with her all her years. Louise not wanting to carry the dollar had her husband, a jeweler and silversmith, mount the coin in a bracelet. Louise died in the early 60's and my mother inherited the dollar. She died in '97 and now I have it.
Besides the family hearsay I have documented the story via a newspaper article in the Reno Evening Gazette. What I desperately need to do is find at least one of the other coins to prove that this story is fact not fiction.
I have no access to the mint records as they were shipped east in the mid 60's from the museum in the mint building. Gov. Blasdel retired to Oakland California and he had two children. A boy and a girl. All are buried in the family plot in Oakland. I find that neither child ever got married or had their own children so have no idea where to look for that dollar. President US Grant? Don't know where to look for that coin either.
So, just a small time collector in Vegas with a coin that may have some history. I would sure like to know if it is a true story or not. So, that is why I posted the WTB thread.
Please keep an eye out for me will ya?
