I attended my first convention some 20 years ago, I kind of didn't realize this until I was thinking about it recently - there will be people who sure as hell have been attending them a lot longer, and back in them days some of the conventions had a star guest - I recall Jeremy Bulloch, Warwick Davis, Paul Blake and (and even then) grumpy Peter Mayhew - and I think with the exception of Mayhew was free (though I believe he was only £5).
Cut to the convention scene now and a free autographs is not very common (though it still exists) and of course there are events (which cost more obviously) that include graphs as part of the ticket price. So the rule of convention now is bring money - sometimes lots - even if you don't buy anything from a stall.
It's incredibly rare that autographs are even as low as £5 now, though in the last year Steve Wickham (Red Dwarf and Doctor Who) charged £5 for 2 autographs and Colin Spaull (Doctor Who) charged me £5 for his, but it's very likely you will be paying at least £10 for a signature even if they was the third Stormtrooper from the right in that one scene (the third Stormtrooper from the right, is a phrase I use regularly, it's not meant as an insult towards bit-part players in the franchise, but rather an example of someone from the Star Wars movie has such a tiny role that it doesn't interest me to get there autograph).
It felt for a while that £25 would be the absolute threshold for signers (which I believe I have only paid once at the time of writing for Ernest Borgnine) and that was for some one who is somewhat of a big name but the price as jumped up it feels more in the last few years and I've seen £35, £45, £75 and even £95, this could be seen as ridiculous but I am off the philosophy - if you don't like the price, don't pay it!
The £95 signer I did see was Sigourney Weaver at the LFCC 2015, whether you agree she is worth it or not you can't argue she is a big name, and if I had been saving I'd pay the £95, obviously only getting the 1 signature (it would have been a choice between Aliens and Ghostbusters - ignoring some other cool roles). I am also of the mindset that you paying for an autograph and experience, so in a lot of ways I can justify to myself paying more for that bigger name.
It's unlikely in my town of Hull, a bunch of big names will not be showing up anytime soon and will unlikely be standing in a barrier hoping that Tom Cruise comes across, and maybe just maybe you can get someones autograph even for a lot less from the likes of eBay (even if you are 100% confident of it been authentic) it's just not the same as much as you would want it to be.
It's hard as a fan to mention the whole convention + charging for autograph thing because as a fan it's not something I feel I need to defend, though I guess I'm totally doing it here, it all seems a bit ridiculous that the cost these conventions have to put in to bring multiple people over and then basically just give it away for free, conventions would be going belly up left and right.
One thing I wanted to mention is the all on-going multi signed pieces, take for example my Doctor Who poster that I am currently working on - when all is said and done I could have spent £100's and will never see it back (even if many of the names where not inscribed to me). Is it a waste of money? It will be to some people but I find a lot of joy in adding names and hoping names from the show pop up at local or affordable to attend conventions.
So I suppose what I'm saying is if you think it's a waste of money this all graphing thing - that's your opinion, there is probably something about you that others will think is a waste of money but if you enjoy it and the experience like I do - just keep doing it.
