Found reference to one similar in "SUPPLEMENTARY TITLE INDEX TO KENT'S VALUATION OF British Coins and Tokens", page 213. Wording doesn't appear to be exactly what is on your token, although I can't totally read the obverse in your picture. The book was published in 1918, here's the link (you can download the PDF if you like, too):

The 60/107 appears to be the number of the token out of how many there are, then obverse and reverse descriptions. The 2/ appears to the value (2 pence?) and ef the grade when at that value. (old book
