There are two different Hard Rock guitar tokens which have the Guitar names mispelled. (I am not a guitar expert)

Info taken from Greg Strathos's information page:

The two errors are:

$10 token - (Guitar) The "1964 - Model 325, Rickenbacker" is spelled wrong. On the token it is spelled "Rickenbacer", (the second "K" is missing) the correct spelling is "Rickenbacker".

$20 token - (Bass Guitar) the Beatles Bass "Hofner" is spelled wrong. On the token it is spelled "Hoffner" (with two F's) the correct spelling is "Hofner".
