Recently excavated from an 1870s privy. The use layer in which this marble sat for over 135 years was mostly early 1870s with a few 1860s bottles mixed in and the parcel which contained the privy was developed in as early as 1867. If I had to guess, I'd say the marble dates to the late 1860's ???? So far it seems that this particular design may be unique, have any of you other diggers/collectors seen a rabbit scene like this before ? The size is 3/4" and the condition is pristine.
