I always assumed that these were gifts usually given to a King, someone of importance. The incense and ointments were likely expensive in their day and only used on special occasion, to those of upper class perhaps?
Here is some more info I found on it...
Matthew 2 tells us that the magi, or wise men, traveled from the East in search of the Christ child. They inquired of King Herod where they might find Him, saying, "Where is He who has been born king of the Jews? For we saw His star when it rose and have come to worship Him" (Matthew 2:2). Upon finding the baby Jesus, “they bowed down and worshiped Him. Then they opened their treasures and presented Him with gifts of gold and of incense and of myrrh” (Matthew 2:11).
Gold is a precious metal and as such was a very valuable commodity. Its value could very well have financed Joseph and Mary’s trip to Egypt. The Bible does not tell us any other significance to these three gifts; however, tradition has it that there is a deeper meaning for each of the three. Gold is a symbol of divinity and is mentioned throughout the Bible. Pagan idols were often made from gold and the Ark of the Covenant was overlaid with gold (Exodus 25:10-17). The gift of gold to the Christ child was symbolic of His divinity—God in flesh.
Frankincense is a white resin or gum. It is obtained from a tree by making incisions in the bark and allowing the gum to flow out. It is highly fragrant when burned and was therefore used in worship, where it was burned as a pleasant offering to God (Exodus 30:34). Frankincense is a symbol of holiness and righteousness. The gift of frankincense to the Christ child was symbolic of His willingness to become a sacrifice, wholly giving Himself up, analogous to a burnt offering.
Myrrh was also a product of Arabia, and was obtained from a tree in the same manner as frankincense. It was a spice and was used in embalming. It was also sometimes mingled with wine to form an article of drink. Such a drink was given to our Savior when He was about to be crucified, as a stupefying potion (Mark 15:23). Matthew 27:34 refers to it as “gall.” Myrrh symbolizes bitterness, suffering, and affliction. The baby Jesus would grow to suffer greatly as a man and would pay the ultimate price when He gave His life on the cross for all who would believe in Him.
