A cut denarius

I received an interesting cut denarius this week. I have not had a chance to ID the coin, but a first pass guess in one of the many Cr53s.
The coin details:
Weight = 1.63 grams
Diameter = 18 mm
The weight of the original coin is low at 3.2 to 3.6 grams depending on how close to half of the coin is here.
The silver coin was cut. Less than half of the edge is irregular. The bronze coins were broken. None of the half asses show cut marks.

 The cut coin fits in well with my half ass collection.

My 5 Favorite Coins

I attended a meeting of ancient coin collectors last week. It was interesting seeing what others collect and some of the stories that went with the coins. For example:

• The obverse and reverse of this coin shows the silphium plant and seed. The plant was known for its medicinal properties, including contraception. (1). The reverse shows something much like modern day valentine heart. 
• 
• I won this coin by bidding from a helicopter flying over Brazil.
• This silver sixpence was worn in my grandmother's shoe on her wedding day.

My favorite five:

The large piece is a Ramo Secco bar

Julia Domna (Augusta, 193-217).

Moesia Inferior, Marcianopolis.

Æ Triassarion

Obv - Draped bust r. R

 (23mm, 8.78g, 7h). / The Three Graces standing—the outer two facing, with heads turned inward, the middle with back facing and with arm around other two. H&J, Marcianopolis 6.17.26.9; cf. Varbanov 887. Good Fine
