Anthoni Grill (19 April 1705 – 22 March 1783) was the son of Abraham (I) Grill and Helena Wittmack and twin brother to Claes (I).
Around 1722, he moved to Amsterdam where he participated in his uncles' trading house, dealing in copper plates and iron and supplying the Dutch East India Company between 1722 and 1731 with silver.

The Dutch had very little to offer in Asia but silver and gold.
Therefore the VOC ships had to sail to Asia with silver bars and gold coins to pay for Asian goods.
The bars were cast in private factories, run by assayers, from melted down coins, mainly from Spanish American "reales".
Once in Asia these bars were melted down and minted again into coins such as rupees, that could be used in the East.

In 1733 he married Alida Jacoba Hilken with whom he had eight children.
In 1735 he cooperated with his brother Johannes (IV) to promote the trade with Sweden.
Spanish pieces of eight were used to produce silver ingots that were shipped on the Rooswijk, which sank in 1740.
In 1742 both brothers lived separately on Herengracht; they each owned a chaise and two horses.
In 1747 they sold the silver melting business at the end of Spiegelgracht, and concentrated on banking and assurance on ships and goods for customers in Sweden.
Around 1751, they moved into the "Huis met de Hoofden" which they rented from the descendants of Louis De Geer.
He wrote twice a week to Stockholm.
When Johannes died - with whom he shared many bills of exchange - Anthoni Grill became the only heir and his other siblings were bequeathed.

The trading house in Amsterdam wrote a bill for the amount for which it bought goods from a Swedish seller.
The seller could then obtain money by selling the bill to someone who wanted to buy goods, in Amsterdam or elsewhere, and use the bill to pay for them.
Importers and exporters both bought bills, in order to pay and in order to obtain money.
Bills that were not cashed immediately earned interest.
A bill that was transferred before it matured was sold at a discount.
The interest due from the transfer date up to maturity was deducted from the bill’s nominal value.
The higher the rate of interest, the larger the discount.

During the Seven Years' War France gave a total of 11 million sd.
in subsidies to Sweden.
In 1759, Anthoni lodged Bengt Ferner, a Swedish astronomer and mathematician, who kept a diary about his travels in Holland.
Accompanied by Jacob Grill, Ferner visited the mint in Utrecht and Harderwijk, run by inlaws.
During the Amsterdam banking crisis of 1763, he was considerably involved in the bankruptcy of Leendert Pieter de Neufville, who failed to come to an agreement with his bankers.
Their financial situation of the clearinghouse deteriorated, because of fluctuating exchange rates in the recent past.
In the meantime the name of the bank changed to Antoni Grill & Soonen.
In 1768, as in 1736, the Swedish mystic, inventor and mining specialist Emanuel Swedenborg visited Grill.
In 1773, Anthoni became owner of the Garphyttan factories when the previous owner (Michael Grubb) failed to repay the money he had borrowed from him.
To be able to manage the factories, his sons Jacob (1734-1799), Abraham (1735-1805) and Anthony Grill Jr (1743-1805) moved to Stockholm.
Their sister Helena Catharina (1739-1804) owned a quarter in the profitable "La Jalousie" plantation along the Commewijne River and stayed in business.
Both her father and Helena were buried in Amsterdam.
