Asked the teller (in the drivevthru) for some nickel rolls for my kid and they gave me several 2017 D rolls which are BU. Is there a market for these (if so, why) or should I just turn them back in? Thanks!
eBay... check sold (not active or simply completed) listings. This is likely your best bet, and is especially true if you were planning on using said site to sell them if there is any demand. That said, while I'm sure someone somewhere has paid up for them, I wouldn't get my hopes too high.
There will be a premium in a few years. People do collect rolls by date if original wrapped MS coins.
Perhaps it would be better to say "may" be a premium... There simply are no guarantees, especially with something like this with no "special" aspects, and there are lots of people out there who've learned this the hard way. State Quarters, anyone? Or thereabouts, but after offering (often) "free" shipping and paying fees, not including any individual hassle involved, the return is fairly modest at best. Still, this is a personal decision, and if something the OP willing to do, I certainly wish him the best of luck.
The sooner you can sell them, the better... the demand for new coins is highest at the beginning of the year they're minted and declines as the year progresses... Other than the 2009 coins (and some of the 2010-2012 quarters), pretty much every year of cents, nickels, and dimes issued in the 2000s has not carried a substantial premium in the years after issue. I've had no problem selling lots of 500 2017-D Lincolns on eBay for $12.99 or so and $6.99 shipping - have sold five so far... After fees, I'm netting about $5 per transaction... so a $25 profit for coins I got for face. I am trying to find more new rolls, but none of my local banks has them at the moment. There was an initial LOOMIS via Brinks shipment of the 2017-Ds that at least four of my local banks got, and they're pretty much gone now.
