wanted Platinum or Palladium graded

[cliveb13]

Morning TSF 

I started out collecting an ‘element’ collection, but thankfully got distracted by PMs & Platinum, Palladium & Rhodium. And then I found gold coins. 
I am looking to cycle back a bit & add any special Platinum or Palladium graded to my collection. 
I’d be keen to what pieces any of you have. I am trying to not be specific . 
I have the 2017 Palladium Eagle (first year of issue), & various parts of the 2007 & 8 Britannia Platinum series in grades. Though neither of the 1oz £100 in 70. I also have the 1/4 run of Britannia Pt from 2017. 
 

thanks . Look forward to hearing from you

I've not yet got a coin beyond gold and silver (not even copper, which seems to be a thing currently). I've always been kind of scared of by platinum as a bit of a niche thing that might be difficult to sell close to spot. I'm considering getting one nonetheless at some point as I like having an indestructible coin. 

What got you to buy the 'elementals'? Doesn't platinum look a lot like silver? Rhodium looks pretty cool, but I figured it'd be more of a one of a kind for a collection than a traditional stacking method and even more difficult to sell adequately. Would you recommend elemental bars or coins?
