I am currently looking to get rid of my clad proof sets. All prices on these are at less than the CPG retail values, which are about what the sets are going for. I have the following prices listed for the years below: 1978-S: $9 1979-S (Type 1): $9 1980-S: $7.50 1981-S (Type 1): $9.75 1982-S: $7.50 1987-S: $7 1988-S: $6.50 1989-S: $6.50 1994-S: $8.75 1995-S: $12 1996-S: $11 1997-S: $11 1998-S: $12 Do note that the case of the 1980 proof set keeps falling out of the black part of the display. Here are shipping rates for each set: Shipping is $1.50 per set on orders up to 4 sets. On orders of 5 sets or more, shipping is $3 per set, due to the fact that it would require a medium flat rate box to ship. However, if you take all 13 sets, total shipping is $18.50. Most of, if not all, of the shipping fees that I charge will go right back into the package. At this time, I am accepting payment through post office money orders. Once the money order is sent and cashed, I will send your proof set(s). The set(s) may take around 6-10 days to arrive. If you are interested, please PM me whenever you can. It may take me a few hours to reply, but rest assured that I will reply. Thank you for looking!
