After releasing the Mr. Gold, Pogo decided to make more gold minifigures. Iron Man Mark 21 Midas is the second chrome gold plated minifig that Pogo made. Other bootleg makers in China had released the Mark 21 before but non had the gold plated treatment. You may order from Aliexpress.
Our beloved protocol droid C-3PO deserved a chrome gold body. POGO 637 C3PO appears to have the torso of the 2016 Redesign but no printing on the legs. Too bad it’s not the 10,000 limited edition from 2007. You may order from Alexpress.
