A brilliant breakdown there from John (argentum)! Personally, I would (or I have?!) start with option 1, and slowly move to option 3! Work on the premise that collecting will inevitably lead to upgrading a coin that you already have, and as such likely needing to liquidate the funds from the lesser coin to put towards more! If you are in the area, I'd be more than happy to welcome you to Reading Coin Club (I am the secretary there!), or if you are further afield, can point you in the right direction of your local club! We're all baying for young blood, so if it is something that you might be seriously looking at as a hobby (and/or business!) it will be well worth it!
