Reinhard von Schoonvorst issued this gulden under the authority of the Lordship of Valkenburg during a period when lower Rhenish lords were aggressively exploiting the demand for gold coinage along the Rhine trade routes. The St. Jansgoudgulden type drew directly on the Florentine florin model that had swept European commerce after mid-century, with regional lords effectively free-riding on the florin's established credibility.
Valkenburg's minting rights were perpetually contested, and production windows were narrow — hence the tight two-year attribution bracket for this issue.
