$.50-$.50 NL hold'em in Pokerroom

I was playing $.50-$.50 NL the other day and I got pocket Aces. Someone raised to $3.00 pre-flop and I re-raised him to $6.38. I thought betting anymore than that might be coming on too strong. He called and the flop came 2 [img]/images/graemlins/diamond.gif[/img]2 [img]/images/graemlins/spade.gif[/img]2 [img]/images/graemlins/club.gif[/img]. My opponent went all-in immediately for $87. I thought about it for awhile but then I folded, putting him on 2 10 or better. Was this the right move? I just started playing poker and I'm pretty confident in my read but I would like some other opinions.
