Apart from that, I haven’t done that many trades that are really ‘memorable’. Regardless, here are some trades I remember as a kid:
My English unlimited holo Jungle Snorlax for an English WB Mewtwo promo
My Legendary Collection Reverse Foil Moltres for an (international version) Ancient Mew [I wasn’t sure either card were real when I did the trade at the time, haha ]
My Ancient Mew for a Japanese Gold, Silver, to New World… (Neo Genesis) Steelix
As for more recent trades, they’ve almost all been done with @mdlsoares. Some duplicated Pikachu of mine that he was at the time still missing, for Portuguese Pikachu autographed by Portuguese voice actors. Some examples of those:
Two Portuguese Pikachu autographed by the Portuguese voice actress for Ash and Jessie for the DP era onward: Raquel Rosmaninho:
That reminds me, I think Miguel has one more autographed Pikachu in his possession we’d still have to trade for.
And my most recent trade, which was last month, has been with @Xyelios, whom had a misprinted French Flying Pikachu V (completely missing it’s smooth texture), which I’ve traded for my semi-glossy Unbroken Bonds Spritzee and Litten.
