The topic has come up before; this thread wasn't too long ago. 
The link I posted before is probably the kind of thing you're looking for: bulk repro pirate coins for 40¢ to 50¢ each or so.
Real ones will stretch the budget a little more: a silver Spanish "piece of eight" will probably cost you $100 to $500, depending on condition. A gold Spanish doubloon will probably set you back around $1000 or so.

Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
