What is 5 Réis?
5 Réis begins with memory.
Its name echoes the Grupo dos Cinco Réis, a small civic association in Lisbon whose modest title referred to the smallest Portuguese coin of its time — five réis — yet whose values were far greater: fraternity, secular thought, education, and cultural participation.
Within this same constellation stood the Grémio do Monte, where voices such as Maria Veleda and Fernão Botto Machado helped shape the intellectual and civic life
of Graça.
It was within this world that, in 1934, Mário Peixoto — Sandra’s great-grandfather — was publicly honoured for a lifetime of civic dedication, at the very moment dictatorship was beginning to silence that generation.
5 Réis is, in part, a tribute to that legacy — and to the belief that culture, integrity, and independent thought are forms of inheritance.
It reimagines value not as capital alone, but as cultural legacy, critical thought, and meaningful exchange.
Art is not simply acquired.
It is interpreted, preserved, and carried forward.

5 Réis is an international art advisory platform connecting collectors, artists, and institutions through curatorial thinking, strategic guidance, and meaningful cultural relationships.
For over two decades, we have worked across acquisitions, collection management, curatorial development, and artist positioning—offering tailored support shaped by expertinse, discretion, a trusted international network of galleries, museums, institutions, auction houses, and private collections.
Our work is grounded in the belief that art is not only an object of value, but a form of legacy.
Every artwork carries cultural, symbolic,
and intellectual weight. We approach each project
—whether building a collection, curating an exhibition, or guiding an institutional collection
—with the same attention to detail, historical awareness, and long-term vision.
For artists, we offer more than visibility—we help shape clarity, positioning, and long-term artistic direction.
Our work begins with understanding the practice itself: its conceptual foundations, visual language, and place within broader cultural and curatorial conversations.
We support artists through curatorial texts, critical writing, exhibition development, portfolio review, strategic positioning, and tailored pathways for navigating the art world with coherence and confidence.
We work with artists not only to present their work, but to strengthen its place in the world.
Services may include:
– curatorial texts
– critical writing
– artist statements
– exhibition concepts
– portfolio review
– strategic positioning
– institutional proposals
– career pathways and long-term advisory

Sandra d’Aguiar Peixoto is an art advisor, curator, writer, and researcher working between nineteenth-century visual culture and contemporary art.
With over two decades of experience across museums, galleries, institutional projects, and private advisory, her practice connects collectors, artists, and cultural institutions through acquisitions, curatorial strategy, collection building, and critical writing.
Her work moves between historical depth and contemporary visual thinking, combining curatorial practice with long-term advisory for both emerging and established artists, private collectors, and institutional collections. She has collaborated with museums, galleries, and international cultural platforms including Fundação Calouste Gulbenkian, Vhils Studio, Underdogs, Festival Iminente, Art Central Hong Kong, and the National Gallery of Victoria in Melbourne, where she acted as researcher and curatorial liaison for an international exhibition project developed with the support of the Portuguese Ministry of Culture.
Writing remains central to her practice. Through essays, exhibition texts, catalogues, and academic research, she works to position artworks and artistic practices within broader cultural, symbolic, and historical conversations.
Currently a PhD Candidate in Contemporary Art at Universidade NOVA de Lisboa, her research focuses on nineteenth-century Portuguese painting and the wider Symbolist questions of image, interiority, and symbolic representation, exploring how these visual structures continue to shape contemporary artistic thought.
Art is not simply collected—it is remembered, interpreted, and carried forward.
