August - November have always been the best for me.
You need to remember it takes time for the old lady dumping her silver for cash to buy Christmas gifts at the bank to full up the bag (could be a day, week or even month), at least a week for the currier to make their weekly pickup, however long it takes for the currier to sort through and roll it, and then depending on how many boxes they already have in reserve combined with how they stack the boxes (new on top of old or old goes out first) it may be weeks to several months before you see Christmas silver cashed in in November or December.
I have gotten dumps back as soon as 3 days later all the way to never seen a certain months dumps come back around after 3 years or more.
