From $7.68 to $16.49.
The Pokemon Trading Card Game XY BREAKpoint series was released on February 3, 2016. About 15-months later, they released a Darkrai EX Tin that included a non-promo 74 Darkrai EX card from that series.
As expected, the market value for that card plummeted to $7.68 in June 2017! Now that those tins are hard to find in stores, the market value has recovery completely, as seen in the chart below:
