To be honest, I could never understand the concept of collecting just one country or a complete set of all coins for a period or Monarch. Some of the coins could be quite unattractive or worthless.....why have them clutter a collection??!! A short lived series YES but imagine collecting different denominations over several years....for me at least, a definite NO. Having said that, I'm trying to complete the Canada sovereign series of George V. I'm missing the two most expensive coins in the series which will cost almost 100,000....so I have a while to wait to complete the set but I will continue to buy other coins from other countries and eras while my search continues..
Of course British coins are fun! World coins are fun to collect, in part because I can afford interesting ones without selling my house. I even like the modern ones that sell for pennies in the junk foreign boxes. I used to teach a world geography course to 9th graders. I would have each one do in-depth reports on a country. I would assign each student a country by having them pull a coin from a sack, having made sure all the coins were from different countries. The students got to keep the coin, for which I had paid 5 or 10 cents at a flea market. They loved it.
George V is a hard one to get in any area of the empire. I collect Fiji pre decimal coins, George V is one hard coin to find in MS. Keep the hunt going you will get there.
I would suggest this is a good example of artistic AND Kings and Queens: Gothic Crown 1847, Undecimo edge.
