David Alves Rebello (1741-1796) was a numismatist (coin collector) and collector of natural history. The first token was struck by him as a promissory token - a substitute coin due to a lack of small value coins - and has his monogram and a picture of Hackney Church where he lived. The second, struck after his death in his memory, has a figure of Time seated on a coin collection.The two rather lovely botanical paintings are by his daughter Rachel (d. 1823) and were previously owned by Margaret Bentinck, Duchess of Portland (1715-1785).Incidentally the Church has no more significance that being a landmark in Hackney where Rebello lived. He was an active member of Bevis Marks until his death.
