Reddit reviews A Guidebook of United States Coins 2014: The Official Red Book

The 1829 half cent might be your most expensive coin. The $80 offer was way below what this entire thing is worth. If you have +600 half dollars, assuming none of them are silver, thats still $300. I recommend you get a red book and look up your coins. The russian paper money is a bit beyond me on value, but I imagine there isn't a strong collectors market for them.

this is one of those cases where the more effort you put in, the more money you get out. I'm sure there are plenty of people who would make you an offer just based on what you posted (i would take a gamble). the price would be pretty low and if you sold it, the person would make a lot of profit. what i recommend to everyone in your situation is to build an excel database and document every coin in the collection. From there, buy a "red book" for ~$10. just that alone will protect you quite a bit from unscrupulous dealers. from there, you can take pictures of the more high dollar coins and we all can help you determine a more exact price. the rest, a dealer will offer you a low price for, because there isnt a lot of profit margin.

Damn, man… buy yourself a US Coins Red Book (go for a spiral-bound version). It'll teach you how to grade the coins, as well as which ones are key dates and potentially worth quite a bit. That 100 Troy ounce silver bar is worth right about $2,500 by itself.

You may want to bring a copy of the Red Book with you next time you go coin shopping. It'll help you familiarize yourself with the prices a bit.

Seriously...I would buy a Redbook and Strike it Rich with Pocket Change and start looking at values. The Redbook gives high values for graded and slabbed coins. You can expect a little less, but it will give you a ball park that can be further compared to completed e-bay auctions.

By "redbook" coin collectors mean this Guidebook of United States Coins which, strangely, is cheaper in hardback than paperback on Amazon right now.
