Having just started collecting, so complete newbie, I am curious as to why people collect (and why me lol). I can see from previous posts that for some its collecting a coin from each year and others it about collecting the best example of a particular coin. I shall just be happy to have a reasonable example of the most common coins from as many different British monarchs as possible; some will be in unc condtion and most definitely not. I am curious however, if its possible to be sold a coin that has been worked up to a higher grade. Does that happen? My interest began when I came across a plastic bin full of old coins in Gloucester Antique Centre. I was helping my 10yr old niece to dig through and find a coin from each 20thC monarch...and I was hooked lol. Great forum btw.
