What is the safest way to conduct a private numismatic transaction?

The private meeting protocol — seven steps

Step 1 — Choose a CCTV location. Bank lobby, hotel lobby, government office, mall. Arrive before the agreed time; orient yourself to the camera positions.

Step 2 — Photograph the note immediately when shown. Both sides, serial number clearly visible. Do this before any agreement, before any discussion of price. This photograph establishes what specific note was presented at the meeting.

Step 3 — Inspect the note yourself at every step. Never let the note out of your sight. When the seller 'packs' it, unpack it and verify the serial number matches the photograph you took. The sleight-of-hand swap happens during packing or handling — vigilance at this specific moment prevents it.

Step 4 — Agree on price. Confirm verbally and immediately send a WhatsApp message to the seller: 'Agreed: [note description], price ₹X, paying now at [location].'

Step 5 — Pay by UPI at the meeting. Show the payment confirmation screen to the seller. Screenshot the UPI confirmation immediately. The UPI timestamp places the payment at the meeting location and time.

Step 6 — WhatsApp confirmation from seller. Ask the seller to confirm receipt: 'Received ₹X for [note description].' A reply or thumbs-up creates the written confirmation.

Step 7 — Photograph and note the serial number one final time after taking possession of the sealed/packaged note, in view of the CCTV. Open the packaging and verify the serial number before leaving the CCTV coverage area.

The sleight-of-hand fraud — how it works and how to stop it

The sleight-of-hand swap is one of the oldest physical fraud techniques in numismatic transactions. The seller shows the buyer a genuine, high-value star note or error note. The buyer inspects it, agrees to buy. The seller takes the note to 'pack it' — puts it in a sleeve, an envelope, or a bag. While doing so, they substitute an ordinary note of the same denomination. The buyer pays and leaves with the wrong note.

Prevention is straightforward: never let the note out of your sight during the packing process. Watch every movement of the seller's hands. When the seller hands you the packaged note, open the packaging immediately and verify the serial number matches the note you inspected. Do not accept the package without verifying the serial number. The seller who refuses to allow verification before payment is a red flag.
