I was on acsearch trying to figure out a price for a Probus coin and was surprised by how ridiculous the prices have been for similar types in the past.
Probus
A.D. 279
Ӕ Antoninianus
22x24mm 3.8gm
IMP PRO-BVS AVG; Radiate and cuirassed bust right.
ROMAE AETER; Roma seated in temple holding Victory and sceptre.
In ex. R crescent Γ
RIC Vii Rome 185
I was thinking about $125; but after seeing these prices I figure at least $1200. ;D
derp...the expensive Probus coins are actually not antoninianii but double antoninianii...the weights are circa 8.5g ::)
