Reference

Thanks to the internet, there is a massive amount of information available on numismatics, notaphily, philately (and just about any other hobby you can imagine).
Below are listed the top sites and apps Loose Change Coins uses on a daily basis to locate essential information on many products. 
Using these tools can help assess the potential value of your collection, or to find out valuable information about that item you have never seen before.

 

NUMISTA:
This has to be one of the most comprehensive online resources for coins/medals/medallions and more that I have ever used. It also allows you to create a personal online collection list that includes things such as: cost, date obtained and more.

AllCoinValues:
One of the most important websites I use to determine the value and different varieties of Australian Pre-Decimal coins. Though the torrent of information doesn't stop there! AllCoinValues also list coins from New Zealand, Great Britain, Australian Banknotes and United States of America Coins.

TDKPDC:
Used in conjunction with AllCoinValues this website is a true gem, with corroborating and supplementing information (and in some cases expanding) on Australian Pre-Decimal coins and their multiple varieties. Most importantly though, it provides an excellent step by step grading system that can be applied with practice to most coins.

COINOSCOPE:
Coinoscope mobile app makes coin identification and valuation easy - just snap a picture of a coin with your phone camera and the app will show you a list of similar coins. Fast and accurate. A must-have tool for every coin collector and numismatist!
