Hmm... let me see..... the biggest pot that I've seen (this was way way way back) was when me and few other people got in a bidding war at the poker tables. The pot? *Sigh* Around 50,000 gold, which, yes, I lost.
The biggest pot I ever won, I believe was around 17,000-21,000 gold. Papa got his War Frigate that night
By the way, both of these took place at the Ratskellar, with full tables.
