Ecuador 1997 100 sucres roll of 20.  Mint uncirculated condition in original roll.  One-year-only design commemorating the 70th anniversary of the national bank.  According to Numista, the characteristics of each coin is: Bimetallic: Bimetallic: brass clad steel centre in stainless steel ring • 3.55 g • diameter 19.5 mm
KM# 101, Schön# 94.

I use these in some penny presses.  On a recent trip to northern Michigan, about half the machines accepted these coins.  These were mainly decades-old machines that did not have strict tolerance levels for pennies.  Newer machines tend to have narrower penny slots and these are too wide for them.
