Where: Rio de la Plata · South America · approx. -34.64, -58.42 (vicinity only)
Why this spot: 1870-1900
What turns up: Golden-age Buenos Aires: Hesperidina, Bilz, Argentine gins and sodas - a deep, rich city dump.
Access: Gray area.
Ley 25.743 makes artifacts over 100 years old state property, so pre-1900 glass is technically patrimony. Enforcement targets pre-colonial material; the Argentine collector scene works demolition sites and old dump grounds openly. Gray, not clean. It is dense urban barrio now - realistically this means watching demolition and utility trenches, not open digging.
