1830 Miraculous Medal Sterling Silver
Front and Back

Found yesterday in a drawer here at home in a roll top desk.
An unusual border on the front. It is cut in such a way to sparkle in the light. I have not seen another like it.
The date does not appear to read 1830 for some odd reason. It looks more like 1820 or 1880 to me.
Incuse stamp on the reverse is an unreadable and crude rectangular area that I do think probably says "STERLING" but may be the result of a deteriorated die.
The date is supposed to read 1830 which is the year that Mary, The Blessed Mother, appeared to St. Catherine Laboure at the Rue de Bac Chapel in Paris France.
When Mary spoke to St. Catherine, she said "Have a medal struck upon this model. Those who wear it will receive great graces, especially if they wear it around the neck. Those who repeat this prayer with devotion will be, in a special manner, under the protection of the Mother of God. Graces will be abundantly bestowed upon those who have confidence."
The design of the medal was seen during the apparition by St. Catherine and the prayer is the wording shown on the front.
The symbolism is correct and easily found searching for 1830 Miraculous Medal.
With approval of the Catholic Church, the first medals were made in 1832 and distributed in Paris. Only ten of the original medals are known to exist, and one of them is housed at the Miraculous Medal Shrine.
Many medals have been made. By autumn of 1834 there were already 500,000 medals in existence. In 1835 there were more than one million worldwide, and in 1839 more than 10,000,000 medals had been distributed. At the time of the death of Sister Catherine, in 1876, there were more than a billion medals.

I do believe this is at least 50 years old and the chain is quite interesting as well. Certainly more than an ordinary variety.
The appearance, weight and feel of this medal and the chain has me convinced it is .925 silver.
