This is typically a pretty easy set...but there are a couple better than others. 1979-P Wide Rim (Redbook: $20 in MS63) 1979-S Clear S Proof is pretty valuable (Redbook: $125 in PF65) All 3 circulation 1981 issues are a little bit rarer because they were mint set only 1981-S Clear S proof is probably the key of the set (Redbook: $250 in PF65) The 1999-P Proof is also a little more valuable as well (Redbook: $30 in PF65) Redbook isn't always the best way to look at values...but I think it gives a decent idea. But, all 1981 and 1999 issues were only made for mint sets...there were no circulation coins those years. So, I personally find those more desirable.
See the other thread on SBA`s. To all that wanna find out about US coins.. Either Buy a Whitman "Red Book" for about $15, or go to your local library and borrow one for free. The "REDBOOK" has pictures of the coins and information on dates, mintages of all US coins. It will tell you what mint minted these coins, and where to find the mintmark etc. The prices listed are only guides to what a coin is worth. But the red book will give an idea as to whether your date and mintmark of a particular coin is common , scarce, or really rare. The values given are usually are usually on the high end of retail, although, this week, gold and silver prices are at new recent highs, and some redbook prices will look low for some gold and silver issues of both recent and older coins......
Actually, 1999 SBAs were made for circulation and did circulate. Main reason they bothered to bring them back was to make sure vending machines could still accomadate them when they went to the Sacagawea dollars the next year (which have the same weight and diameter as the SBAs). However 1999 mint and proof sets did not include them (the Philadelphia mint did mint proofs that were sold as a separate product.)
