  a worn Buffalo might work, but I try to play this early machine with the 
correct coin for its original period of operation (Liberty/V). The only thing I 
have "changed" is that I have avoided using sulphuric acid in the original 
battery jar, and substituted (invisibly) a small power pack inside which 
converts 
120 AC to 3 volts DC. The bottom shelf, however, is still lined with lead 
sheeting from 1890. The interior safe has a partner's lock - which requires two 
keys to get the nickels out. Also popular at that time were phono tokens, 
pre-purchased by the user. I use that too.

  Just over 1000 of this early device were made, but perhaps 7 survive.
