So it looks like a couple of you are playing along and it's nice to see. I won't give anything away just yet!
This is a 2015 philharmonic 1oz coin. Like all these coins in CODTPIR, it were purchased back in 2015 when I was first starting out.
It was bought from ebay as BU, direct from a mint tube but it did not come with a capsule.
Over half way now boys and girls.....
Thanks for playing along and good luck
