They should do fairly well until the next shakeout and then it will depend
on how the newbies embrace them. Look for at least a few years of good
growth. They are attractive coins and have a lot going for them. Most were
destroyed through the loss of their date in circulation so even common dates
are desirable.
Earlier quarters also make a logical stepping stone for states quarter collectors.

Similar situation with proof indian head cents. Dealers will scoop 'em up (the ones I talk to anyway) at bid levels right now, if they don't have any problems, ie: spots etc.

I expect to continue to see strong pricing advances especially on certain dates.
16 of course(the demand for this date is intense when a nice example comes available) there are some dogs, even slabbed,so be selectful and willing to pay the strong money for the right coin.
19-s with full or nearly full heads are still undervalued compared to sheet levels (Au grades and up)
19-d is another tough and underrated date.
1921 in lower to mid circualted grades are going to go up considerably in upcoming year(MY Opionion) these are very tuff and underrated.
I think the 27-s in XF and lower end AU's are currently priced strong, with little movement upward expected. A lot of people will probably disagree with me on this one, but I have seen typical average strike XF, and AU's struggle to bring even ask levels.
On the other hand ,really PQ upper end AU's and higher are another story, these get truly rare especially with full to near full head details with solid strikes.
The other dates, I am not that familar with and current on !

Also, some of the coins are dark and thus look ugly. Any eye appealing SLQ is selling above grey sheet ask level. Take a look the ebay results. For tough date (19D, 19S, 23S) MS65 flat head with good looking, dealers are asking 50% over ask and they are selling.... The problem is that even go to Long Beach show, you hardly find one or two nice looking 19S MS63 or higher coins, and J. Cline is there also.
Usually, the way to grade SLQ is also an art since some of the date/mint is typically weak struck. Unless you know the series very well, you should stick with PCGS SLQs. The NGC coins are usually 1 to 1.5 points higher in grade. Most nice NGC/ANACS/PCI SLQs are crossed-over to PCGS holders. Nevertheless, I saw many SLQ dogs in PCGS holders and they are circulated among auction houses forever.
If you would like to buy any Full Head coin, make sure you know what the Full Head is. If you are so tough about Full Head definition, some dates, such as 16, 24S, 27S, almost do not exist. There are too many 90% Head coins that are in Full Head holder and dealers are asking Premium to sell them. When the time to re-sell them, sure to take a loss.
Just my 2c worth after viewing more than 3000+ mint state SLQs.
