"I consider that you have individually tackled a task that most collectors of Irish coins have avoided or been unable to tackle. And the key to this was your identifying that many of these coins were languishing unidentified as English coins, and this combined with the development of the internet coin market ... has meant that you have been able to assemble a lot of examples and have been able to start identifying them by the portraits and styles so that pieces with virtually no legends can now be properly identified as Irish." - John Stafford-Langan
