The two bottles you found there look to be early 1900s citrate of magnesia bottles from local druggists or pharmacists. I don't know the exact value or rarity but i do know that most green citrates are scarce bottles and most slugplate citrates are scarce also, so i would say they are probably fairly valuable bottles to a local collector.
Yeah, I will second the citrate of magnesia. Too bad that green one is beat up! I bet it's a GOOD one! It would be cool to have some other bottles from the same druggists for a display.
Yeah too bad about the green one. The mason and beach business goes back to the 1870's, there are a lot of different druggist bottles out there from them, but this is the first time that I seen these two. The green bottle was the best but as you can see, it is bruised in the front and there is a crack in the back on the inside. If they are after 1900, maybe that is why we haven't seen them in the privys that we have dug here so far. I guess we will have to keep digging.
