Waheguru Ji Ka Khalsa!, Waheguru Ji Ki Fateh!! all,
A big thank you to Serjinder Singh for making a number of valid points with references included.
I just wanted to add a few bits to this topic for those interested:
Some gurdwara's even today in India, do provide a token coin for people holding an Akhand Paath, however, these do not have pictures but show text, Khanda, etc,.
And, anyone thinking of collecting Sikh coins please do research these first, as a lot of so called "Sikh Coins" being offered by some on-line auctions and from Pakistan & India are fake.
I myself bought some on on examining them closely did I realise they were in fact NOT genuine. In fact I was even offered what the seller called "Authentic Sikh weapons" which at first looked genuine and only by research did it become evident they were well made fakes. Please don't be caught out by these scrupulous people....
The real coins are fantastic, available in gold, silver & copper/brass, reading them can be difficult, not because they mainly have Persian text (the International language of the day, certainly for the Gold and Silver ones). The copper / brass ones do have Gurmukhi on them.Reference:: Sikh Philosophy Network http://www.sikhphilosophy.net/sikh-coins/36656-rarest-coin-1804-pic-shree-guru.html
However, because the whole couplet text was on a dye larger than coins, the whole couplet cannot be read complete on a single coin also the mint marks are the most complex of northern India. Most do however show / read Guru Nanak & Guru Gobind Singh-ji/ Akaal Sahai etc, the picturesof GuruJi's are not used, only on some; symbols of Leafs, Peacocks, Seeds, Katars, and many others things.Reference:: Sikh Philosophy Network http://www.sikhphilosophy.net/showthread.php?t=36656
Also please be aware of many mis-conceptions presented by Non-Sikhs as they have failed to grasp the Sikh understanding in terms of reasoning. And the most exciting thing is new things continue to be atributed to Sikh coins even now, there is still much unknown about them.
As per the general common couplets on Gold Silver coins:
Deg Teg O Fateh Nusraath BeaDirang, Yazt Aaz Nanak Guru Gobind Singh
Sikha Zadh Baar Harr Doh Alam Fazl SachchaSahib Ast Fateh Sat Guru Gobind Singh shah Nanak Wahib Ast.
Gurfateh & best Regards,
