Went to the show today. Spent about three hours and surprisingly, it was quite good this time!
The stuff being offered as same as before, but I saw more variety this time, and pricing was also OK. Few dealers had foreign coins too, but all common. Picked up couple of nice error ₹10 coins (bimetallic) for a good price. Many dealers were having errors (Republic India), seems that these are now being made on order basis.
Also picked up a FDC from India Post's counter issued on occasion of Sachin Tendulkar's 200th Test.
Mumbai Mint's counter saw a good business (it was the only stall which was accepting cards, rest all cash!). Saw lot of people buying sets from them, and the staff was very nice: Smiling, answering to all the questions neatly and what not. Quite unusual for government servants.
NGC (US), PCGS (Europe), Steven Album (US) and one more foreign dealer (mostly fantasies) had their own stalls. NGC and PCGS did good business, I heard.
Overall, it was a good experience, expected it to be dull. Recommended if you are from Mumbai!
