Is there a lot of silver in the British coins? What languages do you write in? I putz around on Code Academy every now and then, it's fun. Can you elaborate on the anarcho-capilast theory? I was an econ major and that sounds interesting.
The main things that I like about British coins are:
1) You can get a lot older coins for CHEAP, you can get low-grade hammered coins for little more than scrap silver, for example I keep a Charles I Shilling in my pocket as a pocket piece, it was minted in the 1640s and I picked it up on ebay for $10, or about $3-4 over scrap at that time (you can't buy an Eagle today for less than that over spot!)
2) All the references are in English and so its a lot easier to understand than something like German coins or ancient coins which have references written in Italian/French/German/English/Portuguese depending on the subject
3) There's stuff for every budget, I can get a simple circulated monarch set from Victoria-Elizabeth II for a couple of bucks and even a set of George I-Elizabeth II is reasonable in low grade. But on the other hand, there's coins with only a handful known, stuff like the Petition Crown, rare proof sets with mintages in the hundreds or tens and even unique pieces.
4) You can be as broad or as narrow as you'd like. You can collect just one example from each monarch, one of every denomination, or you can specialize just in one series such as bun head pennies.
But yes, there's a lot of silver, anywhere from silver Celtic units that are 2000 some odd years old, to medieval silver pennies, to early milled silver, to even modern maundy or silver proof sets. Sterling silver was the standard up until 1920 when it changed to 50% silver until 1947 when it was changed to copper-nickel for circulation coins (but silver coins are still struck for collector issues)
As for coding languages I mostly do Java, but I do dabble in Python and a couple other languages.
As for anarcho-capitalist theory it basically states that the services currently provided by the state (defense, etc.) could be provided by the free market instead. Murray Rothbard is considered to be the real founder of the movement, but there are several others. The Mises Institute is probably the best economic reference for Anarcho-Capitalist theory
