Is there a place where I can search by KM number? I bought a lot of coins that all have numbers but no other labeling and I don't know what country some are.
KM coin numbers refer to the numbering system used by the Standard Catalog of World Coins, originally written by Krause and Mishler (hense the KM). I found it here, or you could buy the book. I collect Ireland coinage and these are KM numbered as well. https://en.ucoin.net/catalog/?tag=km
Numista also does by km # just put km-12, or any number in the search bar. https://en.numista.com/catalogue/index.php?r=km-12&ct=coin&im1
Thanks, I'll try those two sources. I can identify 99% of countries but some Indian states for example I'm just not good with.
Y'know, I've used the Numista search lots of times, but I never thought to use just the KM number . That works fine.
Here is a very limited photo ID page I have found helpful for IPS coins. http://worldcoingallery.com/countries/India_all1.php
So most of the coins I can't ID have numbers that don't follow the KM format. They're either like Y11.1 or K43A. I tried searching those databases and couldn't find them.
Numista is my "go to" also. I also use coinscope for unknown coins. Simpy take a photo with your smart phone (if you have one).
