This one just get's into this category at US $250 including hammer fees and delivery, quite scarce in this condition, Divus Antoninus Pius, Rome 161 AD, AE Sestertius 32.2mm, 25.24gm, Large Enclosure/altar. RIC 1272.
Like $300-$350-ish it was listed for if I recall? I traded several coins for it so I kind of sort of paid $0 for it. Galla Placidia, Western Roman Empire AE nummus Obv: D N GALLA PLA-CIDIA P F AVG, female, pearl-diademed bust right, wearing necklace and earrings Rev: SALVS REI-PVBLICE around cross, T in left field Mint: Rome Mintmark: RM Date: 425-437 AD Ref: RIC X 2111
My Hostilian (as Augustus during the short time of his joint reign with Trebonianus Gallus) belongs into this category as well. To keep my old coins from boring you, I took some some new pictures under the kitchen lamp IMP CAE C VAL HOS MES QVINTUS AVG - Laureate, draped and cuirassed bust of Hostilian right SECVRITAS AVGG SC - Securitas standing facing, looking right, her legs crossed, placing right hand on head and resting left arm on column Sestertius, Rome ca.

I found that I have at least 19 coins which cost around $300 - here are some of them: This new-style Athens tetradrachm came from a CGB auction in 2004 - flatly struck and the original listing said it may have been overstruck on an earlier coin, but little enough wear - it was €250. €276 from a Kuenker auction in 2010, with a provenance to a 1930 Ars Classica auction, this Neapolis didrachm (I don't know what the white stuff is): $291.20 including fees for a Nero auerus seemed a good deal in a CNG e-auction in 2010. It is a contemporary Indian imitation and the reverse legend seems garbled; the best reference I can come with is "cf RIC 25, 31, 36, 40": This was an ugly coin to spend €250 on in 2010 from Grotjohann, but it is a very rare denarius of Otho (RIC 2 - 1 of 7 known), which has had a small hole drilled into an edge as part of published research on the metallurgy of Otho's denarii: £287 for this Lysimachos tetradrachm in a 2013 Roma sale, from the Tanenbaum collection (who was Tanenbaum? - I remember googling him at the time, but can't recall any findings now): This photo' is from the seller and so better, though smaller, than my efforts. I was happy to get this Augustus/Gaius denarius in 2016 for £319 from Naville: The last one is from this year - €263 from CGB for this Memmia 10/Crawford 427/1 denarius. She deserves a better photo' than this 'phone effort: Sorry for length, it was hard to leave some out ATB, Aidan.
