My family and my families friends collected all the predecimal Victorian coins in the late 60's for me (I was a slip of a lad) By the time I was 16 (late 70,s) I collected and bought what I could afford...mainly UK copper. The rest is history....I've collected hard and then dropped it for Girls,Bikes,Cars,Beer,Career...BUT ...always returned. Where do I look for coins? Everywhere....from Car boots,flea markets,coin fairs,dealers,ebay......no hard and fast rule (my tastes are a bit more expensive nowadays).....use google initially....it is worth asking elderly reletives. It's all good luck and part of the fun. This site has a reasonably priced selection of mainly UK coins (where you won't get burnt by the Ebay sharks) A good starting point methinks. Enjoy
