To set the scene, I've been collecting the Zombucks bullion rounds from Provident since they came out. I was wondering how best to display them, and came across a great suggestion in another forum. Basically the display will have the Zombuck round and the coin that was the inspiration for the Zombuck round (eg Trade Dollar, Barber etc). So I will need to purchase 10 US silver coins in the end. Having not bought any US numismatics, I'm interested in any suggestions of where people think would be best to purchase. I'm based in Sydney, I'm happy to buy from reputable online dealers but won't go near eBay. Any suggestions are appreciated.
