I went to a show yesterday and some dealers were selling Ikes for a buck and a half. So the answer is yes...but it depends. SBAs, unless you have the wide rim variety, aren't worth a premium at all.
I have always said "collect what you like". I don't collect for someone else, it's for my enjoyment and entertainment. If it makes a profit down the line then fine. But until then the profit is my enjoyment of ownership. I like Ike's.
There are no SBA left at the Mint. It took the Mint about 20 years to get rid of all the original SBAs, but they struck the 1999 as they finally ran out of the 79-81.
There are so many SBA's in high grade they don't bring a premium. The 1999 SBA's were struck to get dollar coins into the hands of the public as the newly authorized dollar coins could not be designed and produced fast enough.
There very well may be now, but that wasn't always the case. I'll grant ya, I'm not sure how you define high grade, but before they changed the grading standards in 2004 an MS67 was quite scarce, and a 68 topped the charts, for PCGS at least, with barely over a hundred out of about 9,000 of them having been graded.
It's still the same for business strikes, 67s bring a premium for any date (big one for the wide rim) and 68 is still top pop for the ones that have a 68. Half the dates 67 is top pop. There's only 137 68s and 120 of them are from the 99 D and another 10 are the 99 P. The 79 P has 1 and the 79 S and 80 P have 3 each. The 99 D is several hundred bucks in 68 and the others are all several thousand
In order to be valuable there has to be a greater demand than there is supply. kind of by definition an unpopular series is not going to have a high demand. And without that high demand the supply overwhelms and keeps the prices low.
If very few were produced because they were unpopular, then they can become collectible later. For example: Chain Cents and 20¢ coins
OF course the SBA's are collectible. When they reissued it in 1999, the P and D are lower mintage. And the S proof is collectible. 1981 was a a low mintage year, all those are collectible. And the 1980 is much lower mintage than the 1979. All the S proofs are collectible. As well as the 1979 wide rim, near date. Look at the list of coins from this page, except for the common coins, all the rest are very collectible. I don't have any 1981s. But I have a few from 1980 and a nice 1999-D. https://www.usacoinbook.com/coins/dollars/susan-b-anthony/
Being unpopular is often key to a coin's ability to become popular. This makes perfect sense if you think about it. Something that is very popular when it's new will be saved in large numbers and will "always" be common but coins that are extremely unpopular do not get widely saved. There will be lots of buyers and few sellers. If people realized how tough some of these SBA's are they'd be a lot more popular. The '79-S, '79 ND, and '81-s are all pretty tough in nice chBU and scarce in Gem.
I didn't realize the Type 2's had appreciated so much. I have the whole set, I assembled it shortly after the series' demise, then added the 99's when they came out. It's a fun, affordable, short set to complete.
