Its actually really hard for me, so many beautiful coins in my collection. I love them all really.
But if push comes to shove.

These babies, probably the biggest one (The £5 coin), not just because they are blingy gold - but because they are beautiful pseudo medievla designs and just look lavish - more works of fine art than coins.
For something a bit more realistic and down to earth - this
Neat and well struck and truly historic coinage.
I think anyone who knows me, knows if its not old or weird, I am not interested.
I love coins. Especially silver, gold and anything really old.
