Don't be discouraged. They are worth exactly what someone is willing to pay for them. I like the look, who minted them & when?
You definitely could get a premium for them on eBay, I have seen people sell toned rounds for higher prices than average rounds.
Well... not much of a premium (about the same as an ASE). Here's a toned one for $47.00: http://cgi.ebay.com/1-Troy-Ounce-999-Silver-Indian-Head-Round-Vintage-/180702580911?_trksid=p4340.m185&_trkparms=algo%3DSIC.OPJS%26its%3DI%26itu%3DUA%26otn%3D5%26pmod%3D320644660893%26ps%3D63%26clkid%3D1707026823699670078
