If you have an unsigned Le Grand Jockey bronze. You have a reproduction. These have been reproduced since he first created this in the 1800's. There are numerous reproductions that are signed by artist who replicated his work, these sell for a good price, depending on the age and who did it. These are all signed. Is there not a signature on yours any where?
Ok, let me know what they find. I found in research that " Original authentic Period Peyrol castings of bronze figural groups sell in the thousands of dollars. Peyrol pieces are often unmarked or marked with a tiny foundry stamp, which leads some unscrupulous dealers to offer newer reproductions at inflated prices. Recasts are still being produced today.
