ROIguy, I just buy whatever they have-all of them. I take them home, go through them, then if it's a small amount spend them. (OH, the looks you get at the fast food joints!) or deposit them, like if $100 or less, if more than $100 at a time, I just put them through the coin machine at my credit union, it's free there.
I generally take the funds out of my credit card, there is no fee at my bank for that, then redeposit the coins through the coin counter there.
No interest from day 1 at my particular credit union. I also look for errors, sometimes, I found two clipped halves and two 1972 Double Die obverses this year and if I remember correctly a bicentennial silver, hard to get, and a 1974-d DDO.
