It's not iron staining the crystals have a honey (ish) color! the material the crystals line appears to be calcite as well and can get very flower like.

Welcome to Mindat!
Bob & Reiner are correct,,, not worth much,,,, but, don't stop looking, if you find a large pocket, the crystals may get really nice.

Broken down into just pieces of the crystal pockets are always good to give to school children to spark their intrest in minerals.
They are worth that at least !

The structures in your specimen have a resemblance to a very fossiliferous (shells?) stone or coquina. If it is completely silicified, there would be no reaction to acids.
Fossils also are a good catalyst to foster an interest in earth sciences.
