Can you guess the average sale price on launch day?
The English version of the Pokemon Trading Card Game Sun & Moon series was released on February 3, 2017, and the Secret Rare 161/149 Ultra Ball quickly became the most valuable card from that series. Here's a chart detailing what that card sold for on launch day, one month after launch, and two months after launch:
|Number of Copies Sold*||Average Sale Price*||
|February 3, 2017||6||$97.32||-|
|March 3, 2017||6||$80.18||-17.6%|
|April 3, 2017||5||$74.99||-6.5%|
|May 3, 2017||TBD||TBD||TBD|
|June 3, 2017||TBD||TBD||TBD|
|July 3, 2017||TBD||TBD||TBD|
The market value for that card dropped 17.6 percent one month after its launch, which is normal. I'm planning on updating this article the day after the dates listed above to find out if the market value regulates.
