Buying based on denomination??

[SeekYeFirst]

Most government minted gold is easy to trade but could some be better than others? Should one get 1oz coins in 50USD, 100Euros, 100CDN or 200CDN? Something about the Euro designation turns me off. I wonder if I had to go to Canada to sell, would the Maple be easier than GAE. Thoughts?

Probably a slight advantage to selling recognizable gold coins in their respective home countries...but not much...I like Philharmonikeras much as GAEs.
