Plates, spikes, bones
Price context
Plates / spikes vary; museum-grade mounts are extreme outliers
Price bands are educational market context for common grades — not an appraisal, quote, or investment forecast.
Collecting status
U.S. private land + docs. Always confirm landowner release or export path, chain of custody, and that the specimen was not collected from forbidden public land. U.S. federal vertebrates under PRPA are not commercial inventory.
