World Coins Online Reference?

The Krause world coin catalogs are nice to have. Here's an experiment: go to the library and get several of them then look up the same coin in each... you think you are lazy. They recalculate for precious metals but some items are not really worked on.

They are a great reference but sometimes they don't worry about updating for years. I got the editions for 1974, 2002 and 2012, just the 20th century versions but those 3 set me back less then $50 at Amazon. Get an older one for reference then look up the prices on line.

NGC has a free online coin catalog with Krause prices. It has a terrible interface, which is probably why people pay for the real paper catalogs:

Numista also runs a collaborative online catalog, with no prices but a much easier interface:

Any world coin catalog, of the sort you are asking about, is not really going to help you much on coin values. Simply put the field is just way too large and any catalog you buy wisuch a catalog will be out of date( assuming you buy it as soon as it is published). All that said reading the other replies...go for second hand copies of Krause.

Yes, buy the book USED at an online retailer. I like the 39th Edition (2012) because it doesn't have all the problems that the 40th edition has (lots of errors). As far as prices it is just a guide. If you're really interested in what something's currently selling for, check the "sold" prices at ebay (do an "Advanced Search" for the coin, and click on the 'Sold' checkbox). Take the information from both to establish a price.

What I've noticed by just deeply delving into ONE nation's coins (South Korea), is that Krause Publications' Standard Catalog of World Coins (SCWC) has MANY errors, just in this one country. The subject line for coins will be off, or the prices are WAY, WAY off (ie, a .30 cent price for a 1999 5 Won coin. This coin only appears in Mint Sets, of which there are only 8,000 in existence. The mint set sells for a minimum of $400.00 USD. So what is the price of that 1999 5 Won coin? Well, it is most certainly more than .30 cents! I have seen them sold at online Korean retailers (raw) for over $200.00 USD.

But.... The SCWC is about the only compendium of prices for world coins that I know about. And unfortunately, (from my experience, only) they do NOT respond to requests for information or letters to the editor to make content-change suggestions. I've tried.

I think what they thought you said is you were going to publish the actual pictures of the price guides on your website. Don't do that,that is infringement. Posting the prices you look up is not. That is what they are there for. I suggest taking a list of your coins to the library and just writing down the prices if you want to go that route. What I do to determine the FMV of a foreign coin is use several different references to get an average price. Ngc world coin, heritage, and finished ebay auctions. Of course you have to factor in the grade of the coin. Good luck on your search.
