What item does the seller typically pour into the buyer's hand during the transfer of property?

During the transfer of property in a traditional ceremony, the seller typically pours dirt into the buyer's hand. This act symbolizes the transference of ownership and the connection to the land being conveyed. The use of dirt specifically serves as a metaphor for the earth and the physical property being sold, emphasizing the permanence and significance of land ownership.

Each of the other substances listed doesn't carry the same cultural or symbolic weight in property transactions. Sand can often be associated with time or the passing of time but lacks the direct connection to land ownership. Water is more commonly associated with life and nourishment rather than the concept of land transfer. Gravel, while related to soil, does not hold the same connotation as dirt in this context. Therefore, dirt serves as the most appropriate and meaningful item exchanged during the property transfer ceremony.
