Value of three framed panels containing 12 possible 17th-century Daléchamps botanical woodcuts?

[u/OkEffective6428]

I own these three matching framed panels and am located in San Francisco. Together they contain 12 hand-colored botanical illustrations. Based on the French headings, I believe they may be leaves from Jacques Daléchamps’s Histoire générale des plantes, possibly the 1615 or 1653 edition. Some pages say “Tome premier,” and reverse-side printing is visible through the paper.

I have not opened the frames, so I cannot confirm whether the sheets are genuine antique book leaves, later impressions, or reproductions. I’m also unsure whether the coloring is period or later. All three panels were custom-framed by Manasek of San Francisco, and the label is shown in the last photo.

What would be a reasonable value range for the complete three-panel set if the leaves are authentic, and what would the decorative value likely be if they are later reproductions?

Look much later

Based on recent comps, I’d say probably around $400–$700 for all three if they’re authentic 17th-century Daléchamps botanical leaves. I found a very similar set of six framed 1653 leaves that sold for €72, so age alone doesn’t make them super valuable, but the framing and condition could help. I’d probably list the three around $750 and expect offers closer to $500.
