Are they asking 10 or 100 times what some think it's worth? I'm sure some here would love to get it if it was super cheap, but then again it's supply and demand. All silver ones sound good since plated things often regarded as cheap I think.
IMO, 10 BTC is a hugely inflated price for an empty bar. However, that is approximately what a 1,000 BTC empty bar sold on ebay.... so I guess that's the going rate. Yes, this guy is trying to say that an empty, gold plated bar is worth 100 times that.
It's common for collectors to over-value their goods.
