Mata Vaishno Devi: Mysterious Dot
« on: May 19, 2017, 06:45:51 AM »
Dear Friends

Recently Mumbai Mint issued a unc set having two coins of Rs 10 & Rs 5 on Mata Vaishno Devi.

The Rs 10 coin of this blister pack contains a mysterious dot between the limbs of the Lion emblem. It is situated just above the Lion  pedestal. It is understood (not confirmed) that this dot is absent in circulation strikes and unc coins.

Regards

Sanjay Kansal

Note: Credit for this discovery goes to Mr Hemant Jain.

Thanks Kansalji for posting this.

Could this be privy mark? Or misplaced mint mark  ;D

It looks to me rather like the dots you sometimes get from hardness tests (Vickers/ Brinell).

Dheer ji

As you are aware mint marks on Indian coins are present on Reverse side; whereas this dot is on Obverse side. Moreover coin is of Mumbai mint but dot mark is now used by Noida.

It is not Vickers as Vivkers leaves a pyramid shape mark. It could be Brinell, but I am not sure. Brinell usually leaves a bigger mark. Secondly Brinell marks are always randomly placed whereas the mark on this coin is nicely placed at the centre of lion between two limbs

If the mark appears systematically (e.g. only on coins in unc sets) it seems likely to be a die mark, so that workers can distinguish "buckets" of coins destined for sets from other coins. If it appears random (e.g. on some unc set coins, but not on others), it looks more likely to be a damaged die, where the placement of the dot is a coincidence. More research necessary, I would say.

Great!

I heard that the dot is present in all two coins unc sets (Rs 5 + Rs 10).

Has someone booked three coin unc set from the mint (Rs 5 + Rs 10 + Rs 25).

 Lets check if the dot is present in three coin set also...

No Dot in 3 Coin UNC set.

I dont restrict my Mobile phone camera only to take pics.  I use the zoom feature to inspect coins under magnifications (3x - 5x) . Please look at your coin under cell-phone magnification under different light conditions. May be dot is visible only at certain angle.

If it is finally confirmed that  the dot is not present in 3 coin unc sets; then it confirm the theory that it is present only in 2 coin unc sets.

In such a case you could be lucky to have a rare variety.  ;D  ;D  ;D  ;D

I understand that the dot is there in Rs10 proof coins also; but not present in Rs10 coin issued as part of  3 coin unc set
