On the left is CUC, tied to the American dollar, so equivalent amounts; top to bottom is sort of $1, $3, and $20. On the right is the local currency, or “CUP”, on a radically different scale. $1 = around 24CUP. Here, top to bottom in USD equivalents are $.21 (yes, less than a quarter coin), $.42, $.84, and $2. I paid $2 American for a bottle of water in the touristy area, and (a half mile away) $.20 – less than an American quarter- for that same bottle in local currency near my Aribnb.
