Great advice by all, which I totally agree with. I've been collecting since I was about 8 and I'm 32 know. I've bought from dealers and ebay and dabbled at selling on ebay for several years. I mostly sold coins that didn't fit into my collection any more or ones I had upgraded. Lately I have started dealing part time. To be honest sometimes I wish I had more money to but stock but I haven't been taking a wage from this business (I still work full time). Instead any profits are used to by more coins for my stock. That way in a few years my inventory will grow to a nice size with hopefully many choice and eye appealing coins. I would love to deal coins full time but as others have pointed out it's not an easy thing to do. As others have pointed out, knowledge is key and take your time. You are still young enjoy the hobby, collect and learn first. As to buying on ebay, I have written a guide on my website which you might find useful: http://www.coinsgb.com/Buying_Coins_On_Ebay.html One last thing to add... If you have any questions just ask, there are many experianced members on this forum with decades of specialised knowledge only to happy to help.
