I agree with the above experts
Costs $75 here in Canada (last I checked) to get a new pasport, its not alot of money...but it aint chump change!
If you are really worried about, or there really is a
huge difference, you may just want to look into gettin a new one. If you show up to customs sweating bullets b/c you're so nervous about it....they may suspect something. So who knows, it may save you some hassel! I know I've been torn into by customs a couple times (here & Europe).
Turns out my dashing charm doesn't work on Italian custom agents.
