I myself and I know there are many others out there know that Sunday is the day where the rarer chips tend to come out and just overall more chips are ending on a Sunday (around 6 pm EST to about 9 pm EST is the sweet spot). Even the $1 chips like you are selling there are more on the weekend. If you think about it, it makes perfect sense. Most people will have a 7 day auction that starts and stops on Sunday night. I am on ebay everyday, multiple times a day and I have to say that in the past three years I have not seen as many chips and people bidding than on Sunday. Just my thoughts on it.
