Hi, need some help to id needed before buying. Korea, 1 Mun, Sang pyong, General Military Office, series 7 ? Also, fake or real? If real, is it worth US$6,00? Thanks

that's what we usually do, even here inside Brazil, to "reduce" shipping costs. that coin came with another 5 modern ones.

Indeed. Here in Brazil the math goes like this for any imported good. (coin price +shipping & handle )*1.6 1.6 = 60% import taxes. then convert to BRL (+- * 5 given today exchange rate) So for example, if a coin costs US$1.00 in US and S&H US$5.00 we have US$6.00 for the coin, with customs taxes that goes up to US$9.6, and then we calculate the price in BRL. So a coins that costs US$ 1.00 in US can easily cost 10 times more here, if it doesn't disappear in the post office... Welcome to third world country...

Hi, updated the coin sizes/weight on main post.

Hi. Not a problem, I understand perfectly. I'm in Brazil and bought it at a online auction from a Brazilian dealer, for about US$6.00. Why? I don't have coins from that period from China and was cheap. (Relative to prices here in Brazil) As far as I know the coin was part of a collection that he bought for sell. Julio

Just got this one, and those holes looks off. It's a fake or real? 24mm x 1.2mm x 3.3g If real, any idea of how much it's worth? Thanks

Hi, I was offered this coins and am trying to verify if it's a fake. Japan, 10 Sen, Meiji year 3. Y#2. 2.6g, 18.4 mm. (should be 2.5g, 17.57mm) He tested for silver, but not for silver content, so don't know yet if it's 0.800. https://en.numista.com/catalogue/pieces15204.html thank you.

Wow, lots on detective work here. Pictures can be deceiving, so what I do can positively read looking the coin with 2.5 mag., now that I know what to look is: Obv: CON__TANTIN_ ???? NOB C Rev: ? - __XER - ??, it would be GLORI -A EXER - CITUS. Positive about _XER not _XERC above the soldiers. Mint: SMT(S?)? Browsing this page, looking for Thessalonica coins wiht _XER - reverse, it all narrows down do RIC VII 199, There are 9 variations of it here: http://numismatics.org/search/results?q=exer+-+citvs+AND+material_facet%3A"Bronze"+AND+mint_facet%3A"Thessalonica"+AND+reference_facet%3A"RIC+VII+Thessalonica+199" this one the seems to be most similar to mine: http://numismatics.org/collection/1944.100.13064 Getting closer?

Hi, From Not in Ric site (http://www.notinric.lechstepniewski.info/index.html) I was told that it would be a RIC VII 199, Thessalonica, as it can be found here (https://www.wildwinds.com/coins/ric/constantine_II/t.html) not from the same die of course. Opinions? thank you

it's about 17mm x 1.9mm Don't know the correct weight. My scale has no decima point for grams. it read 3g / 0,1 oz, could be anything between 2.3 and 3 g...

Hi, Have this for many years and want to have a more precise id. What I was told is that it's a Constantinus II follis, c. 337-340, reading: CONSTANTINUS IVN NOB C GLORIA EXERCITVS SMTS<something> (the S in TS looks like a Greek sigma depending on how I look at it...) Is that right? Any catalog code? Also, how do you grade it? I have not a clue about ancient coins. Thank you.

Hi. I would like some opinions about this piece. KM#526 Would it be a modern counterfeit? Antique counterfeit? Its data: 39.1mm x 3.9mm x +-24g Reeded Edge Catalog data (Krause): 38mm x 3mm x 27.7g, Lettered Edge As you can see there's a fingerprint imprinted on it. Any info would be appreciated. Thank you.

Hydrogen Peroxide is. Thanks

Both kinds are available. The one that I use actually contains both acetone and ethyl acetate. So far no harm noticed in any metal. Take a long time though, around 24 hours.

My mistake, i meant AD, i.e. CE, thank you. I'll try with a friend of mine who's a chemist. The reason why pure acetone is controlled here is related to it's use in drugs production...

Hi, I've got these two coins, a Kanishka I circa 150 bc and a roman Constantinus II circa 340. Both contaminated by PVC. So far no surface damage present, only sticky to touch. How can I remove it safely? We have no one who do that here in Brazil, so I'm on my own. Common coins I do it with acetone (nail polisher remover as 100% pure acetone is not available for sale without a special permit). Thank you in advance.

Going to my album. Not easy to find them here in Brazil. Will take some time to complete both 50 States & America the Beautiful. So, they're satin(ish) but not the official satin finish, right? Thank you very much.

Utah

Got this ones in a swap.They show signs of being circulated (scratches, etc...) , particularly the White Mountain National Forest with some wear at the hair area.I guess it wasn't supposed to be as they're only released in mint sets, so, s mint apart, are the below Utah & New Mexico satin finish or regular?If so, how to value them? If not, how to spot the difference? thank you.
