I too live in Illinois. And here I would say forget finding anything in rolls or bags. You might, but not likely. I've got accouts in 5 different banks and all agree that the employees have first dibbs on anything that even remotely looks valuable. I used to get 2 to 10 rolls every week or so. I stopped since I haven't found anything worth saving for years. Note all the different types of armored car companies around here? They too all have relatives that are now into coins so not much chance at all anymore. I used to just enjoy spending halves to watch people say WOW, look, a half dollar or Hey what is this? Most banks around now will not even carry those anymore. Bank of America, recently purchased most banks in the area, told me they will soon not accept bulk coins from customers unless they are willing to do the following. Place them loose in a Bank of America plastic bag, sent out for counting, pay for this service, wait until the amount is entered into your account. No account? No take the coins pal. Two banks in the downtown area of Chicago also told me they will not accept bulk coins.
So if your in the Illinois area and ever find a Silver coin, consider yourself a real exception.
