I really enjoy hunting IKE's and used to have a great source of $1,000 bags. Anyone around Jacksonville FL looking for IKE bags let me know, I no a teller who'll get them for you. However, I don't think clad IKE's will ever be worth more than they are right now. If you can't get more for $1 for them right now just spend them. Good luck.
I think most coin shops will pay something extra for them, but probably not much more than $1.20 or so, if that. You might try selling them on Craigslist at a small mark up as well. They seem to sell ok on ebay, but if you are only making a few cents per coin, it really isn't worth the time I don't think.
No need to "just spend them". You can sell them on Craig's List for $1.10 pretty easily. You said you have a few hundred dollars, so that's $20 - $30 profit, and you wouldn't walk by a $20 bill on the ground, so take that $20 - $30 profit.
