Hello Victorian Philatelists
Here's my First Cents Issue. Sadly, I'm missing #16.

I got the three #17's from a BC dealer last year and I'm trying to remember which was what. I'm pretty sure the last two are:
#17b brown and #17 red lilac.
But what's the first one. It's grey!
So I figure it must be #16 and I'm $3,500.00 richer than I thought.
Could someone please set me straight?
Thanks
