If you are looking for a silver coin with 1 btc loaded on it, I highly recommend getting yourself a 2013 Silver or Gilt Silver Casascius 1.0 BTC.  There are a few options here on forum.  You could check dazedfool's thread, he has some super nice ones listed.  If he still has the one with the first bits 1Ag1 it is an excellent example.

minerjones could probably find you one or has one available in their warehouse.

I also have a few Casascius Silvers I would part with for the right price.  Do some research on forum and PM me if interested in one.  My last one, shown in the original post of this thread, sold for 1.8 btc recently so I consider that market price.

Best of luck with your search.

Edit to add:  If you want, I could fund the Sol Noctis with an additional 0.99 btc giving it a total balance of 1.0 btc.  :-)
