Info on Bottle Hunting???

I wasn't sure where to post this.I have heard alot lately about looking for old bottle dumps and how some bottles can go for alot of money.What type of bottles are these???I remember growing up there was an old limestone quarry that ws turned into a park and on one of the hills near a busy street that I used to play on there was alot of old looking bottles.Some were small,blue colored and some were clear.I also remember finding what looked like a gold colored makeup thingy with a porceline type picture on the front of it.Unfortunately I remember smashing some of the bottles on the rocks.I think I will go there tomorrow with the Detector and see what I can find.I think people used to throw their trash down this hillside.Any help with value of bottles would be appreciated.
