Platinum isn't as widespread for investing in as gold/silver is, however there are a lot of reasons why mints don't produce it. The blank costs are higher, as it has a much higher melting temperature than gold or silver, and its also harder and more difficult to machine. You can find silver bullion for $1-2 over spot value for a 1 oz coin, ~$10 over spot for gold, but its more like $50 over spot for Platinum. Custom die setups are much harder I'd imagine as well.

The Cas coin went through the washing machine quite a while ago, probably 2014 anyway, but I still hold a grudge.

Also! Here is the photo gallery of the process to produce the deathstar, Ill post it and an explanation of whats going on in the OP.

The 3D model is printed, cleaned up, and attached to a sprue, it is then put inside of the steel flask. Investment powder is mixed and put under vacuum to pull any air bubbles out that might stick to the model. After it dries, it goes through a 12 hour burnout, ramping up to 230C for the first hour, and then 3 hours after that. Then increasing 150C/hr up to 730C (~1350 degrees F) at which it stays for 4 hours, until the model is finally done, and ramped down to the casting temperature at around 500C for 2 hours. The silver is then melted, and when done, the flask is removed from the oven, placed onto the vacuum casting table, so that when the metal is poured, the vacuum pulls the molten metal into all crevices of the mold, and then is left to cool before being quenched in a bucket of water, and finished/polished.

That would be awesome and I'd surely pick one up if you do decide to make those. You'd probably be the only one that has made platinum wallets for BTC, fitting though.. Both can survive most things

Go for it, is my vote!

I figured we'd never see a Platinum coin here.  I know few mints are set up to do them..and I BELIEVE the price of platinum is too volatile as well for mints to want to produce coins on a consistent basis.  I wonder how many non-gov mints make plat. coins?  When did this horrifying event occur with the Cas btw? My condolences...yeeshh.  Sorry to interrupt auction.

Not to spoil too much, but after putting my 2013 gold/silver 1BTC Cas coin through the washing machine, water/fire resistant wallets have been on the to do list. Silver/Gold/Platinum/Paladium/Rhodium wallets with engraved keys perhaps? Mints wont produce platinum coins for people, and there are relatively few government mints that are setup to make platinum coins. However, with a hydrogen torch and a laser cutter, I shouldn't have "too" much trouble. As long as you don't have a 5,000 degree house fire, it should be pretty safe.

Love to see this, great stuff that you create Salty and I can't wait to see what you'll do in the future .
