One numismatist offers me these two coins, please help me, whether the coins are ok and whether the price is fair. Decentius follis, weight 3.5 gr, diameter 21 mm, price 80 eur Crispina sestertius, price 150 eur Thanks.
The Decentius seems legit. The price seems a little high given its condition, but prices in Europe tend to be higher than in the states, so that may be what you'd need to spend to acquire one. You might shop around a bit on VCoins to see what others examples sell for. Maybe search for "Decentius Chi." I don't know enough about Crispina sestertii to comment on its authenticity.
I think that IF the Crispina sestertius had a legible VENVS FELIX inscription on the reverse, it would be a good price, given its overall eye-appeal and condition. I paid $65 US for this one in 2010: Crispina, AD 177-182 Roman Æ sestertius; 18.62 g, 30.9 mm Rome, AD 180-182 Obv: CRISPINA AVGVSTA, bare-headed and draped bust, right Rev: VENVS FELIX SC, Venus seated left, holding Victory and scepter Refs: RIC 673; BMCRE 424; RCV 6011; Cohen 40; MIR 21
I gave about $80 for my Magnentius many years ago and Decentius is harder to find. So that price does not seem unreasonable for that coin. Really can’t say about the sestertius.
The reverse on the Magnentius makes it a desireable coin for even non-collectors, so the price reflects the demand. Not bad imho. The price on Crispina seems high. I have a shoddy Crispina As which I purchased for $5 in 2012. It's probably still only worth $5. CRISPINA Ae As OBVERSE: CRISPINA AVGVSTA, draped bust right REVERSE: CONCORDIA S-C, Concordia seated holding patera and cornucopiae Struck at Rome, 177-191 AD 5.2g, 24mm RIC 675
And it seems to me that the coin is a little tooled. Thanks to everyone, I'll think about Decentius follis.
1st coin is pretty cool, rare emperor, cool chi-rho, as others have said, looks legit. I think you payed a bit much on the Crispina, looks slightly off by me, but I'm no expert.
