So, how much will coins bearing these two run me? I have to do a research paper over Caesar in Gaul and Britain and have seen pictures of coins with at least Vercingetroix on them, and now I'm really interested.

I am not as up on Celtic coins as I would like to be yet, but Bouddica's tribe were the Iceni, and that is what I would use as a search parameter on Vcoins ~ Ancient Coin Mall to find coins issued during her lifetime.

here is the Wildwinds page of Vercingetorix coins issued by L Hostilius Saserna. Prices run from a couple of hundred dollars to much more!

Here is a link to coins issued by J. Caesar that show a long-haired captive on the back (which may or may not represent Vercingetorix).

Here are more coins showing Gallia (female personification of Gaul) after the conquest.

If you want an actual Gallic piece with Vercingetorixs inscription on the coin, you are looking for a gold coin of the Arverni, La Tour 3774, 3775, 3777, or 3778. I've never seen one for sale and would not want to guess at a price.

As close as I've seen is listed here: CGB auction gold stater

It brought a winning bid of 4900 Euros in 2002.

Many assume the figure on the Roman piece is Vercingetorix, but it is more likely a prototypical Gallic male (as is the female on the companion denarius). It is at least collectible (roughly $1,000 for a decent piece and climbing fast for a nice, well centered piece). I'm not as familiar with the British pieces, but I believe they are readily collectible (maybe a few hundred dollars?????).

Boudicca does not appear on any coin. The head on her staters was a crude copy of a Roman coin. This is the only example I have of an Iceni coin with a head (they mostly have pairs of opposing arcs.) The coin shown was atributed to Boudicca by R.D. van Ardell.
