Coin value newpaper?

[SilverJack]

I sold some proofs that I found will CRHing and the guys in the local shop used what appeared to be a newsprint flyer to determine their value. Any idea what that publication is? If so, can just anyone get a subscription? I guess I could ask them but I thought it was better to just ask here and continue to look like the noob to them.

Thanks in advance for your reply.

They referenced the Greysheet (more than likely). You can subscribe here - http://www.greysheet.com/web_order/subscribe_form.asp

Most likely, the costs for the subscription won't be worth it.

He used the Grey Sheet or Coin Dealer Newletter but you can double check the values here http://coinauctionshelp.com/United_States_Coin_Mintages_Price Guides.html
