A Stamping Ground

Boruch: Mazel tov on finishing Seder Nashim and half of Shas with daf yomi!
Shimon: Thank you. Our continued learning should be a tremendous source of merit for the salvation of klal Yisrael.
Boruch: Amen. In honor of your siyum, I want to show you this Israeli stamp I just bought. It is misprinted with an upside down Shas.
Shimon takes the stamp from Boruch and admires it. He unfortunately accidentally tears it.
Boruch: It’s a good thing you just started Bava Kama which deals with the laws of damages. You know you owe me $1000 for damaging my stamp. It is virtually worthless now.
Shimon gasps and says: But the face value of the stamp is only ten shekel! I understand that to you, it’s worth more. However, I remember someone damaged my neighbor’s metal candlestick, and the posek said the amount of damages that had to be paid was rather small. A used metal candlestick isn’t worth that much even though it had much sentimental value.
