Centennial Liberty Bell Coin/Token Found. Not sure what it is. Please HELP!

Doc1.pdfI found a coin/token while taking down the plaster walls in my house built in 1901. The face is George Washington and reads "The Constitution Adopted Sept. 1787." The back is the Liberty Bell. At the bottom it reads "1887 Liberty Bell" and the rest reads "Proclaimn Liberty throughout the land....Constitution's Centennial"....Would anyone be able to help figure out what it is. I've looked for it online and cant find anything like itREV Bell.pdf ​
