The 5BTCs were Nickel, rather than brass, all 2012
Series 1, with the same 'printed on' error hologram, as the 2011 series 1 error 1 BTC
Series 2, with the same 'windowed' hologram, as the 2011 series 2 1 BTC (no error)
I am sending a couple of series 2 5's to the graders today (turnaround time at ANACS is currently 3 - 4 weeks). These are for a friend of mine, but I know they will be looking to sell once returned. If you are still looking when they get back from ANACS, I will give you a shout.
Thanks for that, I'm not familiar with the 5BTC coins. Updated title.
I have PM'd you.
I should also add that good quality non-graded coins will take preference over just graded, unless it has a good grade.
