Galanterie "Procédé, présent, propos très aimable, qui manifeste l'intention de plaire aux femmes ou de charmer, séduire une femme."
"Ne refusez pas ce que j'ai de meilleur, ma façon de faire la cour à une femme, de lui prodiguer les tendresses fugitives, les menus soins, les petits cadeaux, les galanteries, les bagatelles nécessaires, et de lui parler une langue inconnue d'elle. Renard, Pain mén.,1899, p. 78."

Au XVIIIe siècle, les "bijoux" désignaient l'ensemble des petits objets d'art décoratif et de galanterie généralement transportés avec soi dans sa poche ou son sac. On trouve ainsi des tabatières, des bonbonnières, des étuis, des nécessaires, des tablettes ou carnets de bal, des navettes et de nombreuses boîtes.

"Présent d’estime, de reconnaissance ou d’amitié, la tabatière accompagne toutes les galanteries, devenant un gage d’amour en arborant le portrait de l’être aimé."

Galant "Qui cherche à plaire aux femmes.
Poli, délicat, attentionné à l'égard des femmes."

Surely this is the context? The giving of small objects in the context of amorous relations of some unspecified kind.

NB "token of affection" also obviously has a metaphorical usage, but historically it has always meant objects, and I think it continues to mean it.

This is not easy to parse because it's a sentence fragment with limited context, but 'objets de galanterie' here is a generic term for decorative household items, probably given as gifts, such as 'étuis et tabatières en papier mâché laqué'.

Here's a very similar sentence describing the items made by a particular company (perhaps even the same one as in Judith's text):

Parmi les objets de galanterie, aussi appelés "bijoux", on trouve fréquemment des étuis variés, des flaconniers, des bonbonnières, des nécessaires, des navettes de couture, etc.

You could also include the French term to add a little color.

Without checking, I feel the adjectives "gallant" and "chivalrous" (> "galanterie") apply to men only.

You might wonder about "tabatière" (snuffbox or tobacco pouch), but women used snuff and still do:

Women using snuff: "In 1561 Jean Nicot, the French ambassador in Lisbon, Portugal, who described tobacco's medicinal properties as a panacea in his writings, is credited with introducing ground tobacco snuff to the Royal Court of Catherine de' Medici to treat her persistent headaches.[2][4] Catherine was so impressed with its curative relieving properties, she promptly declared the tobacco would henceforth be termed Herba Regina (Queen Herb). Her royal seal of approval would help ***popularise snuff among the French nobility***.[2][5]" (Wikipedia article on snuff)
