Hemang, Iām no expert on Indian locks, but I can tell you from a collecting point of view that itās hard to tell the ages of your locks as there are copies like them on Ebay all the time. Another thing that will affect value is working origional keys. I collect American,English and German padlocks and have shyed away from Indian locks because of all the fakes or reproductions on the market. It is cool that you have locks that once belonged to your ancestors, something that will be worth holding onto and passing on to your children. Mark
