Thanks to all for your insight. I've decided to keep the white and have all four coins the colored silver. I've since got the 2014 Caribou and it looks quite well as the other two, so just one more to go and I think it'll look pretty nice.
I had the display made up by a fellow in the USA and it costs about $100 Canadian to have it made and shipped up here, and I definitely think it's worth the cost. If you're interested, just send me a private message and I'll send you his info.
Cheers
