Riz Ortolani I Giorni Dell'Ira value

The catalog shows a few different versions of the Riz Ortolani "I Giorni Dell'Ira" music. The full-length vinyl LP, "Riz Ortolani – I Giorni Dell'Ira (Colonna Sonora Originale Del Film) (Vinyl, LP) (Stage & Screen)," has a used sold value of $374.98 [1]. In contrast, the 7-inch vinyl single, "Riz Ortolani E La Sua Orchestra – 怒りの荒野 = I Giorni Dell'ira / Fino All'ultimo Colpo (Vinyl, 7") (Stage & Screen)," has a much lower used value of $4.42 [2]. The other two listings are unpriced in the catalog, so I cannot provide a specific value for them based on sold-comp data.
