I would love to see some Legendary set of coins with holograms of avatars of some of the oldest accounts.
Like a bitcointalk history set.
I had an idea to make a set of plaing cards with some of the established members' avatars, but again lack or time is what stopped me.
Don't make me pinch this idea too

I'd probably buy a set if someone did this.
Honestly, if this project is feasible I don't think I want to pick the users who get it. I might request theymos to actually do that. After all, he's the one that's had more personal exchanges in the background.
Denarium might be a good person to contact. They seem pretty active and the have a contact link on their site (I'm happy to do this if you don't want to).
Noted, thanks for that. I'll see if they would be interested in a project like this. The 3 listed in the OP would likely be my first choices as long as we can strike a good deal, but I have a feeling I'll need some backups.
Not sure if this has been mentioned but I was thinking that a bitcointalk plaque could be made (at an expense of say $200) out of brass or pewter and given to a user for a certain number of merits (like the YouTube plaques) when we more commonly see people with 10000 merit it would be quite a nice way to go I think.
That's actually a neat idea. Again, it doesn't really mean anything if it hasn't got the stamp of approval from theymos to be official.
