Also been produced and minted in gold http://www.nzmint.com/coins/shop-online/batman-75th-anniversary-14oz-gold-coin
Gold mintage is 750. The NZ Mint has 80 left in stock and Apmex has 6. Looks to be a sellout by tomorrow.
$720 aud plus postage, that's a fair whack over spot. Will these things appreciate that much? How do the 75th anniversary Superman coins compare?
The 2013 gold superman coin has done well. The 2014 not so much but there is still appreciation. Not really a fan of Batman though.
It would be good to see this coin sell out in 24 hours (65 to go). I'm still waiting to see some of these pop up on the Bay to really know what kind of premium they will draw.
