http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=320455171641&ssPageName=STRK:MEWAX:IT I was browsing through buy it now or best offers on ebay and came across this one. I'll post scans of the coins when I get them in the mail.
Well the 3 Peace Dollars at today's spot are worth aproximately $44.57 in melt value and you paid $50.00 for all so I wouldn't be to concerned.
I'm not familiar with the nickels or the large cent and judging by the picture of the large cent it looks not so nice. I see the price of the 1914-D in G condition is pretty high.
If the 14-D is in at least good condition you've doubled your money. I'd say you've done fairly well for yourself...
This is not a huge sum of money. You at least shouldn't lose too much, and you stand to make a little. No worries.
