Personally, I feel that it is early in the W series that you can even get these at very reasonable costs. Other than the 06W, which is around $120 give or take, the 07W is around $26 - $30 and you can get the 08W from the mint until the end of the year. The 06 reverse proof will be pricey in the $200-300 range. So lets see here - what would make up a complete set IMO - Proof 1986 - Present (including 06 reverse proof) UNC - 1986 - Present W series (burnished) - 2006 present (don't worry about the 95W - dreaming only) I showed my business partner my complete set back in 2006. She loved this set so much that she went out and put together a complete proof and unc set up to 2007. She did not get the 2006 ASE three piece set which I am trying to convince her to buy. It is a very easy and flashy set to put together. I don't remember how much she paid but it wasn't much.
