I hadn't written earlier on this subject, as I thought for sure someone would have written back with this U.S. note. The 1886 $5 silver certificate has five Morgan silver dollars pictured on the reverse - four of them showing the coins' reverse and one in the center showing the obverse along with the 1886 date under Lady Liberty.

I also believe the National Gold Bank notes have gold coinage depicted on the back of the notes. I haven't added the value of the coins up, but Clifford Mishler has written in his book Coins: Questions & Answers that they add up to $211! I imagine there are more notes and coins with coinage on them as well.

Vignettes of coins of the Spanish American colonies, and less commonly those of homeland Spain, were used on many US obsolete notes. As such they may have served as indications of value to a public justifiably reluctant to accept paper money. Spanish coins were familiar to United States residents, and they were esteemed widely for uniform and high quality and stable value.

Spanish coin vignettes were used on our colonial currency as well as obsolete notes.

This exhibit examines a selection of post-colonial US obsolete notes that have depictions of Spanish coins.
