My collecting goals for each year are set by the US Mint and the UK Royal Mint based on what they actually decide to release to circulation for each year.
Thanks to a good collector friend in the US, I am current 2012 US coins.
While I still need UK coins going back to 2010, despite me living in the UK.
Will collect coins from other countries if I seem something that sparks my interest.
For example, I had to get a 2012 10 Years of the Euro - 2 Euro coin from Greece when it looked like they might stop using the Euro.
I did complete my circulated Franklin Half dollar set.
