Personally I love these coins . Simple but effective design and their history adds a bit of magic/ mystery
Value/cost/price is all relative . Don’t rely on the fact that it may be loaded and just go for the numistic value to you.
Do you think .05 BTC is a little high?
As minerjones says - YES.
You can’t really be expected to pay x2 - x3
I’m no expert , and prejudiced as I said earlier.
Sorry , hope this helps a bit
