Regular-sized, Brown Mirror Holofoil, Black-backed Coin featuring Doduo awarded to those who won three matches in a row in the Doduo Tag side event at Japanese Challenge Road '99 held on June 10-11, 1999 in Osaka, July 18 in Fukuoka, July 23 in Hiroshima, July 26 in Sendai, July 30 in Nagoya, August 3-4 in Tokyo, and August 10 in Sapporo
Because the coin was distributed at an event, there is little circulation, making it difficult to obtain. Is it actually Imakuni? One of the interesting points is that this one is later than the Doduo coin.
