Rob, like me, will get multiple queries a week from ebayers and other MOP's asking if coins are real and what they're worth. I assume (dangerous as that makes ass out of u and me) that Rob, like me, gets totally pissed off with it. We learnt the hard way and the expensive way. We made mistakes and then we taught ourselves with the help of others and at substantial personal cost by buying more books than coins. My own reference library runs into the Thousands of Pounds, Rob has an even larger library than me! Giving advice on here to fellow collectors is okay but giving advice for other people to profit from is a bit like asking your local plumber to fit your heating for free as you support the same team as him?
One off life changing purchases is obviously a reference to the fact that there are very few purchases you will miss by not being clued up that will not come around again.
You come across as both offended and slightly offensive, chill out, it's supposed to be a hobby and hobbies are supposed to be fun ;-)
