He gave two silver tubs to Menelaus,
a pair of tripods and ten pounds of gold.
His wife gave other lovely gifts for Helen:
a golden spindle and this silver basket
on wheels; the rims were finished off with gold.
Odyssey 4. 128-132.
Gift suggestions for the woman you hope to marry: "a splendid robe,/embroidered, with twelve brooches all of gold / pinned to the fabric" or "a necklace, finely worked in gold, /set in with amber beads that shone like sunlight" (Odyssey 18.292-296)
A gift-giving pro-tip: do not get anybody a pair of horses, unless you know for sure that they have an easy way to take them home. "You keep your lovely horses here; I cannot transport them all the way to Ithaca". Odyssey 4. 601-602.
For the awkward young man on your list, drop a little hint by gifting him a special hand-woven nightgown that he can hope to regift to his putative future wife: "the most elaborate and largest robe / that shone like starlight under all the rest". Od. 15.106-7
