This is a 10 Rupee Peacock issue bundle — a serial-wise packet of 100 notes from a single Reserve Bank of India governor. The peacock reverse gives the issue its name, and some packets also include a sought-after fancy number such as 786 among their notes.
Collectors value full Peacock bundles because a complete 100-note run in original serial order, from a single signatory, is far harder to find than loose notes. A packet that also holds a popular fancy number like 786 adds a second layer of interest for number collectors.
What a bundle like this is worth depends on the signatory, the serial run, any fancy numbers and the overall grade — crisp uncirculated packets sit well above handled ones. Coinbazzar lists verified 10 Rupee Peacock bundles so you can check the signature, serials and condition before you buy.
