Well your button find definitely has some age to it Maedadee.
What I can tell you is that it's a second quarter, 19thc two-hole button made of brass, if it had been a four-hole it would've been closer to 1900 in date.
Your button was made by W. B. FENDICK, at 67STRAND, W.C, LONDON in the 1870 - 80 period.
Here's a clearer pic of it.
That's exciting, I appreciate your help identifying it. On the same property my daughter had found a small London double decker bus I know the time frame don't add up but it's interesting to see the two London influences in the same area. Thanks again.
