As several of you are discussing the availability of particular reference books and their cost, I wanted to be sure that you were aware of a tremendous library of old and FREE material.
When Mackaydon gave the link to info on Woodcock's bank, he tipped you off in case you have not used this resource.
.........and the resource is Google Books
http://books.google.com.
If you go to the site and click Advanced Search to the right of the search box and select Public Domain Only, you can find more works of interest in PDF that are complete and free to download than you can possibly imagine.
After reading this post, I went there and in just a few minutes had downloaded the following books:
Provincial coins, tokens, and medalets issued in Great Britain, Ireland,and the Colonies --1798
Appendix to Batty's descriptive catalogue of the copper coinage of Great Britain, Ireland, British Isles, and Colonies --1898
The silver tokens of Great Britain and Ireland --1866
Trade tokens issued in the seventeenth century in England, Wales, and Ireland --1891
Tokens issued in the seventeenth century in England, Wales, and Ireland --1858
I hope everyone is already using this as the big G has made it possible for us to build substantial libraries at no cost, regardless of our field of interest. But if you are not using it, take a look...it's massive.
Unfortunately, the one Cru' references does not seem to be in the group, perhaps due to being reprinted.
Disclaimer: At least, public domain is pre-1923 in the States. Not sure of the laws in other places.
Feast away.
