   Munroe Brothers was a drug store at the time.
   They dealt with trade tokens having denominations in one cent, two and half 
    cent, five cents, and ten cents.  The one cent and five cent looked created 
    from copper, while the two and half cent and ten cent versions were silver
    colored. The different denominations averaged 20mm but varied as the one 
    cent one was about 17.3 mm and the ten cent variety was 23.5 mm .

[In 1919, 5 cents would get you a good cigar based on the newspaper ads of the time: 

"City National, a good cigar for 5¢ at Munroe Bros." 

"Take a few doses of Chamberlain’s Tablets as directed for indigestion, and you 
will soon forget about your stomach troubles. Try it. For sale by Munroe Bros."
