Rob, You'll probably find they'll acheive 40-80% of the catalogue values on ebay, often they go for less. Perfect year sets with absolutely no tarnishing are slightly more popular. I personally think that those kind of things are just a money making machine for the mint, they rarely hold there value and I have paid too much for a few of them in the past. I have quite a few in my specials area and they sell maybe 4 a year at those reasonable prices. Send me a list and i'll give you the cat values and make an offer for the lot.
