Here's one for and from the Land Down Under! Coming from the Perth Mint's site, they'll be releasing two silver dollars that on the reverse side, you'll get an Transformers: Revenge of the Fallen designed Optimus Prime or Megatron! Yes, they're legal tender, yes, 99.99% pure silver, both will be coming in a unique packaging that'll double as a presentation case and numbered certificate of authenticity. Release dates will be July 14, but considering Transformers' popularity, there WILL be restrictions on how many can be ordered, especially large quantities. Each will be going for $88.64 AUS ($70.21 USD) at their site!
