Here are two historical exemplars of each alphabet, from which we can see the difference.
Spencerian is recognized by its "light" lower case letters (the majority of the lower case letters do not have a lot of shading, or heavier thick parts).
Copperplate letters are written with more shades (darker, heavier lines where the pen swells).
