my primary dump bank has a quick change machine (like the one above originally posted by cards). It will absolutely eat 10K coins in about 3-4 minutes. The problem, as mentioned above though, is when you have to wait for a teller to change bags... but thats also a good time to check progress on the bag of halves

(they only have one bag designated for halves on this machine). I'm also still trying to figure out the light system on the machine (it has two lights on either side of it that show the tellers when its getting close to needing a bag change). The issue I have yet to figure out still is which denomination each light pertains to... and how much coin can still be taken when each light turns on. I have dumped a grand with several of the lights on in the past without filling the machine up. But on the same note I have started dumping with no lights on only to have the machine fill up moments later- go figure
