This is like a who's who of silver rounds I covet. Great stuff.
That Britannia looks to be in good shape, the quality of those have been spotty this year. I predict good looking 2013 Britannias will fetch a nice price in the future.
2013 is actually the first year that Britannias are .999 Silver. Before 2013, they have been .958 (Britannia) silver. All of my coins are in Brilliant Uncirculated shape, unless otherwise mentioned. The Britannias are straight from the roll and placed into airtites using gloves.
Your 2000 (Type 6) Liberty Dollar is one of the early "Small E" pieces.
I can offer you a collector's special of a trade for a 1999 (type 3), or alternatively one each Bitcoin Specie and New Liberty Dollar proof strike?
I love trading, pmed.
