Do you happen to know the approximate age of this cobalt blue bottle bottom? My 5 year old found it on a Puget Sound shore while we were sea glass hunting. It's not very frosted, which makes me wonder about its age.

Large cobalt blue bottle bottom found on beach
Most likely it is about 50 to 60 years old. The glass could have found its way into a tide pool for the majority of its aging years, where there is not much tumultuous water and sand movement.
I myself have just found a piece of a Phillips Milk of Magnesia bottle, and is worth around 700 dollars. Since your daughter's piece is an edge/bottom piece, and it hints at its origin, it is probably worth quite a pretty penny as well.

One of the problems we have with glass on Puget Sound beaches is that there is not enough surf to really weather glass properly. If your piece was found in fairly protected waters it could be quite old and still not look "aged".
That being said, your piece looks like it may have been square or triangular which suggests to me that it may be from a "Phillips Milk of Magnesia" bottle.
